00:02:48Ancient astronaut theories
00:06:33C'est-à-dire que la femme de la femme de la femme
00:06:34weighs about 1,000 tonnes.
00:06:37C'est obvious que ces stones
00:06:39ne pouvaient pas être moved
00:06:40en utilisant la technologie et la technologie
00:06:42de l'époque.
00:06:43Aujourd'hui, avec modernes technologies
00:06:46et modernes machines,
00:06:47ils ne pouvaient pas être moved facile.
00:06:50Donc, pourquoi créer des monuments
00:06:52en utilisant ces grandes stones
00:06:55quand les petites stones
00:06:56sont plus simples ?
00:06:57Qu'est-ce qu'ils ont utilisé
00:07:00ces stones ?
00:07:02Et comment ?
00:07:24Dogu literally means
00:07:26earthen figure.
00:07:27They're small humanoid
00:07:29and animal figurines
00:07:31made during the latter part
00:07:32of the Jôman period
00:07:33about 14,000 to 400 BC
00:07:36of prehistoric Japan.
00:07:39Dogu come exclusively
00:07:41from the Jôman period
00:07:42and were no longer made
00:07:44in the periods thereafter.
00:07:47There are various styles of Dogu
00:07:49depending on the exhumation area
00:07:51and the time period.
00:07:53according to the National Museum
00:07:56of Japanese History
00:07:57the total number found
00:07:59throughout Japan
00:08:00is approximately 15,000.
00:08:03Dogu were made across
00:08:04all of Japan except Okinawa.
00:08:08Most of the Dogu
00:08:09have been found in eastern Japan
00:08:11and it's rare to find one
00:08:13in western Japan.
00:08:14The purpose of the Dogu
00:08:16remains unknown.
00:08:18Due in part
00:08:20to the enigmatic nature
00:08:21of the figurines,
00:08:23there have been numerous theories
00:08:24of the nature regarding
00:08:26their ornate appearance
00:08:28with some speculating
00:08:29that the physical appearance
00:08:31is connected to the suits
00:08:32and equipment of modern-day astronauts.
00:08:36One proponent in particular,
00:08:38Erich von Donegan,
00:08:40has written how the Dogu
00:08:41has modern fastenings
00:08:43and eye apertures on its helmet
00:08:46an attribution made as part
00:08:48of the final chapter
00:08:49of his 1968 publication
00:08:52Chariots of the Gods.
00:08:54There are also disparities
00:08:56in the varieties of Dogu
00:08:58with only a portion of the figures
00:09:00having the characteristic
00:09:02goggle-like eyes
00:09:03which are most cited
00:09:05by ancient alien theorists.
00:09:08Were these depictions
00:09:10of ancient aliens
00:09:12or simply fertility figurines?
00:09:15Why did they appear
00:09:16in only one period
00:09:17and then no longer seen?
00:09:20What was their purpose?
00:09:22Who did they represent?
00:09:45The stone doors in Hampi
00:09:47are an impressive pair
00:09:49of monolithic doors
00:09:50that were a part of one of the
00:09:52entrances of the Royal Enclosure
00:09:55in Hampi.
00:09:56The stone doors are one
00:09:57of the outstanding remnants
00:09:59of the Vajangnagar duration
00:10:01that can be visible
00:10:02around many of the ruins in Hampi.
00:10:05Though the huge doors
00:10:07are no longer connected
00:10:08to any shape
00:10:09and aren't purposeful
00:10:10in any manner,
00:10:12they do not fail
00:10:13to capture the interest
00:10:14of the traffic.
00:10:16The stone doors in Hampi
00:10:17had been a part
00:10:18of the Royal Enclosure.
00:10:20The enclosure
00:10:22became a fortified area
00:10:24that changed
00:10:25into the middle
00:10:26of the Vajangnagar Empire.
00:10:29Some speculate
00:10:30these doors were not carved
00:10:32but rather poured
00:10:33and molded into shape.
00:10:35What technology was used
00:10:37to create these stone doors?
00:10:39And why use stone
00:10:41when wood would have been
00:10:42lighter and easier to move?
00:10:49It is not an attempt
00:11:13to move.

00:15:12Perhaps the most famous and enigmatic crystal skull
00:15:17was allegedly discovered in 1924 by Anna Mitchell Hedges,
00:15:22adopted daughter of British adventurer and popular author F.A. Mitchell Hedges.
00:15:28Mitchell Hedges claimed that she found the skull
00:15:31buried under a collapsed altar inside a temple in Leviton,
00:15:35in British Honduras, now Belize.
00:15:38The skull is made from a block of clear crystal about the size of a human cranium.
00:15:44The lower jaw is detached.
00:15:47In the early 1970s, it came under the temporary care of freelance art restorer Frank Dorland,
00:15:55who claimed upon inspecting it that it had been carved with total disregard to the natural crystal axis
00:16:02and without the use of metal tools.
00:16:04Dorland reported being unable to find any telltale scratch marks
00:16:09except for traces of mechanical grinding on the teeth,
00:16:13and he speculated that it was first chiseled into rough form,
00:16:17probably using diamonds, and the finer shaping.
00:16:21Grinding and polishing was accomplished through the use of sand
00:16:25over a period of 150 to 300 years.
00:16:29He said it could be up to 12,000 years old.
00:16:33The skull was examined at Hewlett-Packard's Crystal Laboratories in Santa Clara, California,
00:16:39where it was subjected to several tests.
00:16:42The labs determined only that it was not a composite, as Dorland had supposed,
00:16:46but that it was fashioned from a single crystal of quartz.
00:16:50They also established that the lower jaw had been fashioned
00:16:53from the same left-handed growing crystal as the rest of the skull.
00:16:58No investigation was made by Hewlett-Packard
00:17:01as to its method of manufacturing or dating.
00:17:06As well as traces of mechanical grinding on the teeth noted by Dorland,
00:17:11Mayanist archaeologist Norman Hammond reported that the holes,
00:17:16presumed to be intended for support pegs,
00:17:18showed signs of being made by drilling with metal.
00:17:23Anna Mitchell Hedges refused subsequent requests
00:17:27to submit the skull for further scientific testing.
00:17:31The earliest published reference to the skull
00:17:34is in the July 1936 issue of the British anthropological journal,
00:17:41Man, where it is described as being in the possession of Sidney Burney,
00:17:45a London art dealer who is said to have owned it since 1933.
00:17:50No mention was made of Mitchell Hedges.
00:17:54F.A. Mitchell Hedges mentioned the skull only briefly
00:17:58in the first edition of his autobiography.
00:18:00He claimed that it is at least 3,600 years old,
00:18:05and according to legend, it was used by the high priest of the Maya
00:18:08when he was performing esoteric rites.
00:18:11It is said that when he willed death with the help of the skull,
00:18:15death invariably followed.
00:18:18In a 1970 letter, Anna also stated that she was told by the few remaining Maya
00:18:25that the skull was used by the high priest to will death.
00:18:30For this reason, the artifact is sometimes referred to as the Skull of Doom.
00:18:36Anna Mitchell Hedges toured with the skull from 1967,
00:18:40exhibiting it on a pay-per-view basis.
00:18:42She continued to grant interviews about the artifact until her death.
00:18:48In her last eight years,
00:18:50Anna Mitchell Hedges lived in Chesterton, Indiana,
00:18:53with Bill Horman, whom she married in 2002.
00:18:57She died on April 11, 2007.
00:19:01Since that time, the Mitchell Hedges skull has been owned by Horman.
00:19:06He continues to believe in its mythical properties.
00:19:10Who made this skull?
00:19:12How was it made?
00:19:14And for what purpose?
00:19:16To date, no one is absolutely sure.
00:19:31The Nazca Lines are a group of very large geoglyphs
00:19:35formed by depressions or shallow incisions
00:19:39made in the soil of the Nazca Desert in southern Peru.
00:19:42They were created between 500 B.C. and 500 C.E.,
00:19:48and no one knows their purpose.
00:19:51Most lines run straight across the landscape,
00:19:54but there are also figurative designs of animals and plants
00:19:58made up of lines.
00:20:00Some of the Nazca Lines form shapes that are best seen from the air.
00:20:05The shapes are usually made from one continuous line.
00:20:09Because of its isolation and the dry, windless, stable climate of the plateau,
00:20:15the lines have mostly been preserved naturally.
00:20:19As of 2012, the lines are said to have been deteriorating
00:20:23because of an influx of squatters inhabiting the lands.
00:20:28The figures vary in complexity.
00:20:31Hundreds are simple lines in geometric shapes.
00:20:34More than 70 are zoomomorphic designs of animals,
00:20:38such as a hummingbird.
00:20:41Other shapes include trees and flowers.
00:20:44Scholars differ in interpreting the purpose of the designs,
00:20:48but in general, they ascribe religious significance to them.
00:20:53Who drew these enormous lines
00:20:55that can only be seen and interpreted from the air?
00:20:59Why design what clearly appears to be runways and symbols?
00:21:04Were these guideposts for an alien race?
00:21:08Or landing areas for some prehistoric civilization now lost to man?
00:21:26It can be hard to resist the allure of a mysterious object found in a context
00:21:32that doesn't seem to make rational sense,
00:21:35suggesting that it's proof of time travelers,
00:21:38lost civilizations, or alien visitors.
00:21:41You don't have to be a conspiracy theorist or a cryptozoologist
00:21:46to marvel at a bizarre computer-like device
00:21:49that dates back to ancient Greece
00:21:51or a 2,000-year-old battery found outside of Baghdad in the 1930s.
00:21:57So-called out-of-place artifacts are often said to baffle scientists
00:22:03and conspiracy theorists.
00:22:05They suggest that scientific efforts to identify their origin and purpose
00:22:10willfully ignore potentially controversial explanations outside the mainstream.
00:22:16After all, it's true enough that science is constantly evolving
00:22:20and we still don't have the answers to many of life's mysteries.
00:22:25But imagine how everyday objects from our own time
00:22:29might be interpreted thousands of years from now
00:22:33if information about how they're used doesn't survive.
00:22:37A lot of artifacts become out of place
00:22:40because their original context might have provided important clues,
00:22:44but the object was moved and that context is lost.
00:22:51When we're so far removed from the original circumstances
00:22:55in which a historical object was created,
00:22:58it's easy to let all sorts of things cloud our conclusions
00:23:01about what those objects represent.
00:23:05How do you explain a sarcophagus lid
00:23:07that appears to show a spaceship,
00:23:09primitive sculptures that look like airplanes,
00:23:12or cave drawings resembling astronauts in spacesuits?
00:23:17Some proponents of the ancient astronaut or ancient alien theories
00:23:21post that intelligent extraterrestrial beings
00:23:25visited Earth thousands of years ago
00:23:28and made contact with humans,
00:23:30potentially influencing their technology.
00:23:33These visitors might have been misinterpreted
00:23:37as gods, the theories muse.
00:23:42The supposed proof of these theories lies in drawings
00:23:46like the petroglyphs of Val Chaminita, Italy,
00:23:50which depict figurines with helmets around their heads
00:23:54that could just as easily be ceremonial headdress
00:23:57or have some other more down-to-earth explanation.
00:24:01Ancient astronaut proponents also cite artifacts
00:24:04like a Mesopotamian cylinder seal
00:24:06that sort of looks like a spaceship,
00:24:09since it's just hovering there.
00:24:12Although the first use of linear perspective
00:24:15wasn't seen in art until the 14th century,
00:24:19so the position of objects on a field
00:24:21in an ancient composition
00:24:22doesn't necessarily mean anything significant.
00:24:27A 1968 best-selling book by Erich von Donegan
00:24:32interprets imagery on the lid of a stone tube
00:24:35belonging to Pascal the Great,
00:24:37a Mayan ruler who died in the year 683 CE,
00:24:42as a depiction of extraterrestrial influence
00:24:45on the ancient Maya.
00:24:47In the center of the frame is a man sitting,
00:24:50bending forward.
00:24:52He has a mask on his nose.
00:24:53He uses his two hands to manipulate some controls,
00:24:58and his left foot is on a kind of pedal
00:25:01with different adjustments.
00:25:03The rear portion is separated from him.
00:25:06He is seated on a complicated chair,
00:25:08and outside of this whole frame
00:25:11you see a little flame-like exhaust.
00:25:14Or Pascal could be sitting on a pillar
00:25:17in front of a stylized temple,
00:25:19among many other plausible explanations.
00:25:21What all of this shows us
00:25:24is the extent of which wishful thinking
00:25:26can alter our interpretations.
00:25:29It's obvious how the helicopter,
00:25:32hieroglyphs, found in Abydos, Egypt,
00:25:35got their name.
00:25:36Those images really do look like modern aircraft.
00:25:39Then there's the Saqqara bird,
00:25:42a sculpture made of sycamore wood
00:25:44discovered during the 1898 excavation
00:25:47of a tomb in Egypt,
00:25:49which dates back to about 200 B.C.
00:25:52Some people have suggested
00:25:54that it might be evidence
00:25:55that ancient Egyptians developed
00:25:58the first aircraft many thousands of years ago,
00:26:01possibly with the help of aliens.
00:26:05The Quimbaya artifacts,
00:26:07a collection of tiny golden figurines
00:26:09found in Colombia
00:26:10and dated to around 1,000 C.E.,
00:26:13look a lot like flying objects.
00:26:17When it comes to investigating
00:26:19out-of-place artifacts,
00:26:21the best tool might be Occam's razor,
00:26:24the principle that the simplest explanation
00:26:26is most likely to be correct.
00:26:30The simple explanation for all these objects
00:26:33is that we've taken a lot of inspiration
00:26:35from our airplanes, helicopters, spaceships,
00:26:38and drones from nature
00:26:40and abstracted birds look a lot like planes.
00:26:44Archaeologists say the Quimbaya artifacts
00:26:47are just highly stylized birds,
00:26:50insects, and amphibians.
00:26:52The function of the Saqqara bird is unknown
00:26:55because very little documentation
00:26:57of the period survives,
00:26:58but no credible evidence of Egyptian aircraft
00:27:02has ever been found.
00:27:04The Klerkdorp's spheres,
00:27:06discovered by miners in South Africa,
00:27:09seemed like they had to be man-made,
00:27:11owing to their supposedly perfect proportions,
00:27:15but they're estimated to be 2.8 billion years old.
00:27:19Does that mean that they're evidence
00:27:21of advanced pre-human civilization on Earth,
00:27:24whether some other species from this planet
00:27:27or extraterrestrial?
00:27:29As suggested by Michael Cremo,
00:27:31author of
00:27:32Forbidden Archaeology,
00:27:34The Hidden History of the Human Race.
00:27:38Though they certainly look hand-carved,
00:27:40these spheres are far from perfect,
00:27:42and most geologists agree
00:27:44that they were naturally formed as concretions
00:27:46formed in volcanic sediments or ash.
00:27:49The grooves were likely produced
00:27:51due to the varying permeability
00:27:53of the layered sediments
00:27:55in which the stones were formed.
00:27:56When the aforementioned Baghdad battery
00:28:00was discovered in modern Iraq,
00:28:02it was really just three distinct objects,
00:28:04a fired ceramic container,
00:28:06an iron rod,
00:28:08and a bit of rolled sheet copper.
00:28:11An assistant at the National Museum of Iraq
00:28:14at the time thought it looked like
00:28:16a primitive galvanic cell
00:28:18and theorized
00:28:19that it was used for electroplating gold
00:28:22onto silver objects.
00:28:24About a decade later,
00:28:25a man named Willard Gray
00:28:27made a reproduction of the objects,
00:28:29put them together,
00:28:30and filled the vessel with grape juice
00:28:32to prove its conductive properties.
00:28:36To the surprise of pretty much no one,
00:28:39a lot of supposed out-of-place artifacts
00:28:41are just forgeries and hoaxes.
00:28:44When images of a clay object
00:28:46resembling a modern mobile phone
00:28:48emerged online in 2015,
00:28:50along with the explanation
00:28:52that it was discovered
00:28:53during a dig in Austria,
00:28:55eager theorists were quick
00:28:57to declare its obvious evidence
00:28:59of time travel.
00:29:00As it turns out,
00:29:01the Babylonokia is a sculpture
00:29:04by German artist Carl Winninger.
00:29:08But what about enduring mysteries
00:29:10like the Antikytherian mechanism,
00:29:12which is believed to be
00:29:13an ancient Greek analog computer
00:29:15used to predict
00:29:16astronomical positions and eclipses?
00:29:19Humans of ancient Greece
00:29:21and roughly concurrent societies
00:29:23might not have had cars,
00:29:25air conditioning, or Wi-Fi,
00:29:27but their technology
00:29:28was often more advanced
00:29:29than many of us imagine.
00:29:31All sorts of things
00:29:33could have been developed,
00:29:34used, and then forgotten
00:29:36as civilizations rose and fell
00:29:38in so much of that
00:29:39all-important context
00:29:41disappeared over time.
00:29:44Archaeology is a puzzle,
00:29:46and without all the pieces,
00:29:48we're often just guessing,
00:29:50which is why it's important to note
00:29:51that scientific consensus
00:29:53can shift and change, too.
00:29:57few conclusions are fully set in stone.
00:30:01So to speak,
00:30:02we never know
00:30:03when we might receive
00:30:04new information
00:30:05that changes our perceptions.
00:30:34The popularity of the ancient Greek
00:30:37ancient alien architect theory
00:30:39has grown to great prevalence.
00:30:41This popularity must be mostly attributed
00:30:44to the televised phenomenon
00:30:46of shows such as History Channel's
00:30:49Ancient Aliens.
00:30:50Some sources of information on the topic
00:30:53are found on websites
00:30:54such as TheAncientAlien.com
00:30:57and archaeology books
00:30:59like Graham Hancock's
00:31:01Fingerprints of the Gods
00:31:02and Andrew Collins'
00:31:03Gobeki-Tepley
00:31:04Genesis of the Gods.
00:31:07No matter the popularity
00:31:08of the theory,
00:31:09it is indeed extraordinary.
00:31:11The belief in the ancient alien architect theory
00:31:14defies all bounds
00:31:15of modern scientific knowledge,
00:31:17rejecting traditional accepted requirements
00:31:20for a legitimate scientific theory sometimes.
00:31:24There is no physical or historical proof
00:31:27that provides definitive evidence
00:31:29to support the theory,
00:31:31and yet it holds.
00:31:33No matter your personal opinion on the theory,
00:31:36it is undeniably rampant,
00:31:38controversial,
00:31:39and extraordinary,
00:31:40and it may very well be true.
00:31:46For those who hold stock
00:31:48in the ancient alien architect theory,
00:31:51explanations abound.
00:31:52For example,
00:31:53at the time at which
00:31:54so many of the ancient monuments
00:31:56in question were built,
00:31:58our perception of the necessary technology
00:32:01was not invented.
00:32:03This begs the question as to
00:32:05how our ancestors managed such a feat.
00:32:09Additionally,
00:32:09many of the monuments
00:32:11Egyptian pyramids,
00:32:12Easter Island heads, etc.,
00:32:14have curiously precise alignments
00:32:17with the stars
00:32:18and patterns of the sun.
00:32:21Without telescopes
00:32:22or geometric equipment,
00:32:24this type of precision
00:32:25seems highly unlikely
00:32:27for humans to muster on their own.
00:32:31Interpretations of cave etchings
00:32:33and hieroglyphics
00:32:35seem to reveal images
00:32:36of helicopter-type vehicles
00:32:38and structures
00:32:40reminiscent of a flying saucer.
00:32:45Had our ancestors
00:32:46not been visited
00:32:48by ancient alien architects,
00:32:50how and why
00:32:51would these images appear?
00:32:54Lastly,
00:32:55there is undeniable similarity
00:32:57between structures
00:32:58that were built
00:32:59hundreds and thousands
00:33:00of years and miles apart.
00:33:03without ever having seen
00:33:05these other locations,
00:33:07how did our ancestors
00:33:08duplicate them?
00:33:11To those who accept
00:33:12the ancient alien architect theory,
00:33:15it seems that the only
00:33:17logical explanation
00:33:18to these mysteries
00:33:19was the visitation
00:33:21of higher intelligence
00:33:22race of aliens.
00:33:26On the other hand,
00:33:27there are many
00:33:28who reject the idea
00:33:29of the ancient alien architect theory.
00:33:32From a technological standpoint,
00:33:35it is true
00:33:35that scientists
00:33:36are still working
00:33:37on figuring out
00:33:38how exactly
00:33:39our ancestors
00:33:40managed such large
00:33:42architectural feats.
00:33:44However,
00:33:45modern discoveries
00:33:46and research
00:33:46has uncovered
00:33:47explanations and theories
00:33:49based in legitimate
00:33:50scientific process.
00:33:52for example,
00:33:53a recent study
00:33:54based out of Egypt
00:33:55led to the discovery
00:33:57that water
00:33:58can be utilized
00:33:58to make the transportation
00:34:00of heavy blocks easier.
00:34:03This sheds light
00:34:04of the question
00:34:05as to how
00:34:06our ancestors
00:34:07managed to move
00:34:08such heavy objects
00:34:09without modern-day technology.
00:34:14Circumpolar stars
00:34:15such as Polaris
00:34:16and lines of rope
00:34:17could have been utilized
00:34:18as a method
00:34:19of aligning the buildings
00:34:20so precisely
00:34:21with star patterns.
00:34:23While scientists
00:34:25and archaeologists
00:34:26acknowledge
00:34:26that these actions
00:34:28would have been difficult,
00:34:29they would not
00:34:30have been impossible.
00:34:32Documents
00:34:33and building plans
00:34:34have been found
00:34:35in places
00:34:36such as Egypt
00:34:37as well
00:34:38describing
00:34:38the large workforces
00:34:40utilized
00:34:40in these projects.
00:34:42For those
00:34:43who reject the theory,
00:34:45they see no actual
00:34:46evidence of its claims.
00:34:47They seek proof
00:34:49in traditional
00:34:49and logical
00:34:50scientific process.
00:34:53Those who believe
00:34:55the ancient alien architect
00:34:56theory
00:34:57are not alone.
00:34:58Believers come
00:34:59from every walk of life,
00:35:00every age,
00:35:02and every socioeconomic status.
00:35:04There is a social fascination
00:35:06with the topic,
00:35:07and it is widely popular
00:35:09across many platforms.
00:35:11Social media,
00:35:13television shows,
00:35:14blogs,
00:35:15and even support groups
00:35:16devoted to the theory
00:35:18allow believers
00:35:19to hold strong.
00:35:21The prevalence
00:35:22of the show
00:35:23Ancient Aliens
00:35:24undoubtedly attracts
00:35:25many to this theory.
00:35:27Movies like
00:35:28The Day After Tomorrow
00:35:29and Independence Day,
00:35:31while not focused
00:35:32primarily on
00:35:33ancient architects,
00:35:34promote fascination
00:35:36with alien conceptualization.
00:35:39All of these platforms
00:35:40make it hard
00:35:41to ignore the topic
00:35:42and allow believers
00:35:43more and more outlets
00:35:44to solidify their convictions.
00:35:57When considering
00:35:58the psychological explanations
00:36:00that may account
00:36:02for belief
00:36:02in such a theory,
00:36:03a few come to mind.
00:36:07Ad ignorantum
00:36:08refers to the idea
00:36:09that something
00:36:10must be true
00:36:11if it's not proven false.
00:36:13This is key
00:36:14in the mind
00:36:15of a believer.
00:36:16Instead of saying,
00:36:17let me show you proof,
00:36:18they instead say,
00:36:20show me proof
00:36:21this isn't true.
00:36:25Hasty generalization
00:36:26is key as well.
00:36:27Jumping to a conclusion
00:36:29based off
00:36:30insufficient evidence
00:36:31is found
00:36:32in nearly every claim
00:36:33within the ancient
00:36:34alien architecture.
00:36:35theory.
00:36:36This ties in
00:36:37with the slippery slope
00:36:38ideas as well.
00:36:40A small idea
00:36:41is conjectured
00:36:42and instead of analyzing
00:36:43or trying to disprove it,
00:36:45the idea snowballs
00:36:47into an entire theory.
00:36:48For example,
00:36:49when considering
00:36:50the issue
00:36:51of how the pyramids
00:36:52were built,
00:36:52some argue
00:36:53that hieroglyphics
00:36:55found on site
00:36:56resemble helicopters.
00:36:58A believer
00:36:59assumes this
00:37:00to mean
00:37:01that a helicopter-type
00:37:02vehicle
00:37:02was present,
00:37:03and since humans
00:37:05did not have
00:37:06that kind of technology,
00:37:08they then assume
00:37:09that an extraterrestrial
00:37:11visitor
00:37:11must have brought it.
00:37:13And so,
00:37:14if they were present,
00:37:15they must have been
00:37:16helping with the construction
00:37:17of the seemingly
00:37:19impossible pyramid
00:37:20construction.
00:37:22Instead of accepting
00:37:23alternate explanations,
00:37:25a generalized theory
00:37:27is created
00:37:28and seemingly
00:37:29explains the mystery.
00:37:32These psychological
00:37:33explanations
00:37:34account for why
00:37:35so many fall
00:37:36into this belief pattern.
00:37:38It seems nearly
00:37:39impossible
00:37:39to reject an idea
00:37:41when everything
00:37:42seemingly fits.
00:37:44The characteristics
00:37:45of pseudoscience
00:37:47are tricky
00:37:47and can make
00:37:48almost any issue
00:37:50believable.
00:37:51Humans seek
00:37:52explanation
00:37:53and the comfort
00:37:53of understanding.
00:37:55When tackling
00:37:56an issue
00:37:57such as those
00:37:57ancient marvels,
00:37:58it is natural
00:38:00to search
00:38:00for any explanation
00:38:02because it defies
00:38:03what we see
00:38:04as possible.
00:38:05This is where
00:38:06the ancient alien
00:38:07architect theory
00:38:08gains so much
00:38:10attention
00:38:10and how it
00:38:11continues to spread.
00:38:13Just outside
00:38:15Cairo,
00:38:15in Giza,
00:38:16the most famous
00:38:17of Egypt's pyramids
00:38:19rise from the desert.
00:38:21Built more than
00:38:224,500 years ago,
00:38:24the pyramids
00:38:25of Giza
00:38:25are monumental
00:38:26tombs where
00:38:27ancient queens
00:38:28and pharaohs
00:38:29were buried.
00:38:30But how exactly
00:38:32did the Egyptians
00:38:33build these things?
00:38:34The Great Pyramid
00:38:36is made of millions
00:38:37of precisely
00:38:38hewn stones
00:38:39weighing at least
00:38:40two tons each.
00:38:43Even with
00:38:44today's cranes
00:38:46and other
00:38:46construction equipment,
00:38:47building a pyramid
00:38:49as big as that
00:38:50of the pharaohs
00:38:51would be
00:38:52a formidable challenge.
00:38:55And then there's
00:38:56the astronomical
00:38:57configuration of
00:38:58the pyramids,
00:38:59which is said to
00:39:00align with the stars
00:39:01in Orion's belt.
00:39:03As well,
00:39:05ancient theorists
00:39:06often point to the
00:39:07fact that these
00:39:08three pyramids
00:39:09are in a way
00:39:10in better shape
00:39:11than others built
00:39:12centuries later.
00:39:14So,
00:39:15are Egypt's pyramids
00:39:16artifacts of aliens?
00:39:25A huge circle
00:39:26of stones,
00:39:27some weighing
00:39:28as much as
00:39:2950 tons,
00:39:30sits in the
00:39:31English countryside
00:39:32outside Salisbury.
00:39:34Known as
00:39:35Stonehenge,
00:39:36the Neolithic
00:39:37monument
00:39:38inspired
00:39:38Swiss author
00:39:39Erich von Donnecken
00:39:41to suggest
00:39:42it was a model
00:39:43of the solar system
00:39:44that also
00:39:45functioned
00:39:45as an alien
00:39:46landing pad.
00:39:48After all,
00:39:49how else
00:39:50could these
00:39:50massive stones
00:39:51have ended up
00:39:52hundreds of miles
00:39:53from their
00:39:54home quarry?
00:39:58No one knows
00:39:59what exactly
00:40:00the meaning
00:40:01of Stonehenge
00:40:02is,
00:40:02but as with
00:40:03all the other
00:40:04sites in this
00:40:05collection,
00:40:05the explanation
00:40:06could be aliens.
00:40:09Instead,
00:40:10scientists have
00:40:10demonstrated
00:40:11it's actually
00:40:12possible to
00:40:13build such a
00:40:13thing using
00:40:14technologies
00:40:15that would have
00:40:16been around
00:40:165,000 years ago,
00:40:18when the
00:40:18earliest structures
00:40:19at the site
00:40:20were built.
00:40:21But would
00:40:22they know
00:40:23to do it?
00:40:30It appears
00:40:31as though
00:40:32the stones
00:40:32are lined
00:40:33with solstices
00:40:34and eclipses,
00:40:35suggesting
00:40:36the Stonehenge
00:40:37builders
00:40:37were at least
00:40:38keeping an eye
00:40:39on the heavens.
00:40:51Teotihuacan,
00:40:52meaning the
00:40:53city of the gods,
00:40:54is a sprawling
00:40:55ancient city
00:40:56in Mexico
00:40:56that's best known
00:40:58for its
00:40:58pyramidal temples
00:40:59and astronomical
00:41:00alignments.
00:41:02Built more
00:41:03than 2,000 years
00:41:04ago,
00:41:05Teotihuacan's
00:41:06age,
00:41:06size,
00:41:07and complexity
00:41:07can make it
00:41:08seem otherworldly.
00:41:11Scientists
00:41:12suspect that
00:41:12over centuries,
00:41:14a mix of cultures
00:41:15including Maya
00:41:16and Mixtec
00:41:17built the city
00:41:18that could house
00:41:19more than
00:41:20100,000 people.
00:41:23With its murals,
00:41:24tools,
00:41:25transportation system
00:41:27and evidence
00:41:28of advanced
00:41:29agricultural practices,
00:41:31Teotihuacan
00:41:32is often considered
00:41:34much more
00:41:34technologically developed
00:41:36than should have
00:41:37been possible
00:41:38in pre-Aztec
00:41:39Mexico.
00:41:42By far,
00:41:43the most well-known
00:41:44of Teotihuacan's
00:41:45buildings
00:41:46is the massive
00:41:47Pyramid of the Sun.
00:41:49One of the largest
00:41:50such constructions
00:41:51in the Western
00:41:52Hemisphere,
00:41:52the pyramid's
00:41:53curious alignment
00:41:54is believed
00:41:55to be based
00:41:56on calendical
00:41:57cycles.
00:41:58What inspired
00:41:59them to build
00:42:00this?
00:42:01could it have
00:42:02been an alien
00:42:03intervention?
00:42:35The enigma
00:42:36surrounding the
00:42:37Moai,
00:42:38Easter Island's
00:42:38fleet of large
00:42:39stone figures,
00:42:41pretty much
00:42:41follows the same
00:42:42narratives as
00:42:43the other sites
00:42:44described here.
00:42:46How in the world
00:42:47did the Rapa Nui
00:42:48make these figures
00:42:50more than
00:42:501,000 years ago
00:42:52and how did the
00:42:53Moai end up
00:42:54on Easter Island?
00:42:58Carved from stone,
00:42:59the nearly 900
00:43:00human figures
00:43:01are sprinkled
00:43:02along the flanks
00:43:03of the island's
00:43:04extinct volcanoes.
00:43:06The figures
00:43:07average 13 feet
00:43:09tall and
00:43:09weigh 14 tons
00:43:11and appear
00:43:12to have been
00:43:12chiseled from
00:43:13the soft
00:43:14volcanic tuff
00:43:15found in the
00:43:16Reino-Recaroed
00:43:17Quarry.
00:43:18There,
00:43:19more than
00:43:19400 statues
00:43:20are still in
00:43:21various states
00:43:22of construction
00:43:23with some
00:43:24completed figures
00:43:25awaiting transportation
00:43:26to their
00:43:27intended resting
00:43:28place.
00:43:28The reasons
00:43:30for carving
00:43:30the Moai
00:43:31are mysterious,
00:43:33though they
00:43:33are likely
00:43:34sculpted for
00:43:34religious or
00:43:35ritual reasons.
00:43:36It's also
00:43:37not exactly
00:43:38clear what
00:43:39happened to
00:43:40the Stone Age
00:43:41Rapa Nui,
00:43:42but a leading
00:43:43theory suggests
00:43:44their civilization
00:43:45succumbed to
00:43:46an environmental
00:43:46disaster of
00:43:48their own making.
00:43:49Nor do we
00:43:50know who or
00:43:51what in
00:43:52inspired these
00:43:53creations.
00:43:54Aliens are
00:43:55also a
00:43:56plausible reason.
00:44:10Outside the
00:44:11old Inca capital
00:44:12of Cusco,
00:44:13a fortress
00:44:14rests in the
00:44:15Peruvian Andes.
00:44:17Built from
00:44:18enormous stones
00:44:19that have been
00:44:20chiseled and
00:44:21stacked together
00:44:21like a jigsaw
00:44:23puzzle.
00:44:23Some say it
00:44:24could be the
00:44:25work of an
00:44:25ancient civilization
00:44:26that had a
00:44:27little help
00:44:28from interstellar
00:44:29friends.
00:44:30The 1,000-year-old
00:44:32interlocking
00:44:33fortress walls
00:44:34are made of
00:44:35rocks that
00:44:36weigh as much
00:44:36as 360 tons
00:44:38each,
00:44:39and which were
00:44:40carried more
00:44:41than 20 miles
00:44:42before being
00:44:43lifted and fit
00:44:44into place
00:44:45with laser-like
00:44:46precision.
00:44:48creation.
00:44:48How an ancient
00:44:50culture accomplished
00:44:51such a feat of
00:44:52engineering is a
00:44:53little problem to
00:44:54solve.
00:44:54In fact, it isn't
00:44:56the only example of
00:44:57this intricate
00:44:58masonry.
00:44:59Similar walls exist
00:45:01throughout the Incan
00:45:02empire, including one
00:45:04in Cusco where a
00:45:05twelve-angled stone
00:45:06has been carefully
00:45:08wedged into place.
00:45:10Did aliens help with
00:45:12or inspire the
00:45:13creation of these
00:45:14monumental structures?
00:45:15It's unlikely the
00:45:17Inca had this
00:45:18technology.
00:45:24The evolution of
00:45:26technology follows a
00:45:27pretty linear path
00:45:28throughout history,
00:45:29but sometimes we
00:45:31stumble upon artifacts
00:45:32that challenge that
00:45:33perception and throw
00:45:35those perceived
00:45:36timelines for a loop.
00:45:39To some, these
00:45:40out-of-place artifacts
00:45:41are none other than
00:45:42ancient alien
00:45:43technology, providing
00:45:45our ancestors were
00:45:46once visited by an
00:45:48advanced race, while
00:45:49others maintain it's
00:45:50evidence we've
00:45:51underestimated the
00:45:52technological faculties
00:45:54of our ancestors.
00:45:56Growing up, most of
00:45:58us were taught that
00:45:59the Egyptians built the
00:46:00pyramids through
00:46:01primitive means, using
00:46:02simple pulleys and
00:46:04brute force from
00:46:05slave labor.
00:46:06But under deeper
00:46:07scrutiny, this
00:46:08explanation doesn't
00:46:10seem to make sense.
00:46:11and the same could be
00:46:12said about the temple
00:46:13complex at Pumapunku in
00:46:15Bolivia.
00:46:18The temple grounds of
00:46:20Pumapunku are believed
00:46:22to date back to
00:46:23between 536 and 600 A.D.,
00:46:26constructed by a
00:46:27civilization appearing to
00:46:29have been wiped out by a
00:46:30cataclysmic event.
00:46:33Pumapunku is part of the
00:46:35larger, well-known
00:46:36Tiwanaku site, an important
00:46:38location to the Incas, who
00:46:40believe it is the cradle
00:46:41of their civilization.
00:46:44Characteristics ancient
00:46:45alien theorists might
00:46:47consider significant as
00:46:48well.
00:46:49This area is marked by a
00:46:51decorated megalithic
00:46:52archway known as the
00:46:54Gate of the Sun, and
00:46:55according to Freddie
00:46:57Sylvia, it may be one of
00:46:59the oldest temples.
00:47:01Once home to somewhere
00:47:03between 10,000 and 20,000
00:47:05people, the name itself
00:47:06translates to naval
00:47:08at the center, implying
00:47:10it once served as a
00:47:11cultural hub.
00:47:13Atop the Gate of the Sun
00:47:15is a carving, the supreme
00:47:17god of the Incas.
00:47:23Sylvia says the Viracocha
00:47:25and his ilk were
00:47:26described as being much
00:47:28different than the
00:47:29indigenous Incas.
00:47:30They were white-skinned,
00:47:32bearded, fair-headed,
00:47:33and capable of bending
00:47:35the laws of nature.
00:47:36They were also
00:47:37significantly taller.
00:47:39And these weren't
00:47:40descriptions of the
00:47:41conquistadors.
00:47:42They didn't come along
00:47:43for about another
00:47:44century.
00:47:47The reports of Viracocha's
00:47:49superhuman race make the
00:47:51anomalous stonework at
00:47:53Pumapunku all the more
00:47:54interesting.
00:47:55Perfect 90-degree angles,
00:47:58precision cuts, and
00:47:59immaculately even spacing in
00:48:02the stones were shocking
00:48:03considering the primitive
00:48:05epoch in which they were
00:48:06made.
00:48:07Much of this craft stonework
00:48:08remains distinct to this
00:48:10day, confounding scientists
00:48:12and archaeologists alike.
00:48:39Earth is probably the last place
00:48:42you'd look for extraterrestrials.
00:48:44especially with all the new
00:48:46exoplanet discoveries and the
00:48:48endless quest to prove there
00:48:50was life on Mars at least
00:48:52once in the past,
00:48:54something billion years ago.
00:48:57But are we looking too far?
00:49:01Some scientists are less out
00:49:03there and more down to earth,
00:49:05literally when it comes to
00:49:07finding traces of alien life
00:49:08forms.
00:49:09Not that these hypothetical
00:49:11aliens are actually crawling
00:49:13around our planet.
00:49:14What these scientists argue is
00:49:16that they may have dropped by
00:49:18before humans even existed and
00:49:20left behind technosignatures such
00:49:23as radios, rockets, or other
00:49:25tech that might have been lying
00:49:27deep underground or floating
00:49:29around in space for eons.
00:49:34Astrophysicist John Wright has
00:49:36elicited more than a few eye
00:49:37rolls with a controversial
00:49:39argument that was recently
00:49:41published in the International
00:49:43Journal of Astrobiology.
00:49:45He believes that technosignatures
00:49:48from an alien species that landed
00:49:50not just on Earth or the moon,
00:49:52but even Mars, before its atmosphere
00:49:55was obliterated, or Venus, before it
00:49:58became a swirl of toxic clouds,
00:50:00could have possibly survived
00:50:02somewhere.
00:50:03While Venusian clouds and volcanoes
00:50:06would have long since eroded and
00:50:08liquefied any shred of evidence,
00:50:10he still believes it is possible
00:50:12something could be buried on Earth,
00:50:14Mars, or the moon, if it hadn't long
00:50:17ago become space junk.
00:50:21If a prior technological, perhaps space-faring
00:50:25species ever arose in the solar system,
00:50:28it might have produced artifacts
00:50:29or other technosignatures
00:50:32that have survived to present day.
00:50:40Meaning solar system artifacts
00:50:42provides a potential path
00:50:44to resolving an astrobiology question.
00:50:49Wright doesn't believe aliens
00:50:50actually lived on Earth,
00:50:52and even if they had,
00:50:53erosion and ever-shifting landmasses
00:50:55would have turned any trace
00:50:57of them to dust.
00:51:02Hypothetical alien trash
00:51:04would have had a much better chance
00:51:07of surviving in the subsurface
00:51:09of Mars, away from the solar winds
00:51:11and radiation it constantly
00:51:13gets blasted with,
00:51:14and too deep to be smashed
00:51:16by meteorite impacts.
00:51:18The red planet also has no
00:51:20plate tectonics to crush any
00:51:22ancient computers or whatever
00:51:24they might have scattered around.
00:51:27Other scientists are more skeptical,
00:51:30possibly because we haven't yet
00:51:31found any prehistoric ray guns
00:51:33or radio transmitters
00:51:35next to a T-Rex skeleton.
00:51:42Astronomy professor Ivi Leob
00:51:44believes that there could have been
00:51:47a visit from other civilizations
00:51:49on Earth.
00:51:50The search for extraterrestrial artifacts
00:51:52is more likely to find
00:51:54technosignatures in space,
00:51:56though, however,
00:51:57unlikely that still is.
00:51:59The most effective way
00:52:01to zoom in on something unusual
00:52:03would be a sky survey.
00:52:05Whether we'd actually recognize
00:52:07something as alien,
00:52:09even if we saw it,
00:52:10is an entirely different thought
00:52:12to keep both scientists up at night.
00:52:16Supporters of the drive to find
00:52:18extraterrestrial artifacts
00:52:20are already peering deep into space
00:52:23in a bid to discover cities,
00:52:25satellite networks,
00:52:26or gigantic megastructures.
00:52:29Some even think our own solar system
00:52:31could contain probes
00:52:33sent by an advanced civilization,
00:52:35wreckage from old spaceships,
00:52:37or even evidence of ancient settlements
00:52:40on planets like Mars or Venus.
00:52:43Yet other experts slammed this headline,
00:52:45grabbing easily sensationalized discipline
00:52:48as entertainment science,
00:52:50and question whether there's any point
00:52:52looking for such tiny needles
00:52:54in the mega haystack
00:52:56of our breathtakingly gigantic universe.
00:53:02A.V. Leob,
00:53:03chair of the Harvard University
00:53:05Astronomy Department,
00:53:06is among the world's
00:53:07most respected astrophysicists.
00:53:10He stunned the scientific community
00:53:12by refusing to rule out
00:53:14the possibility
00:53:15that a strange cigar-shaped object
00:53:18which sped through our solar system
00:53:20may have been alien in origin.
00:53:26Astronomers named the space rock
00:53:28Uma Omura,
00:53:29Hawaiian for scout,
00:53:31and said it was an interstellar visitor
00:53:33which formed in another star system
00:53:35before traveling here
00:53:37through the void of deep space.
00:53:39He did not simply dismiss the idea
00:53:41that it was built
00:53:42by an extraterrestrial civilization,
00:53:44and suggested it could have been
00:53:46a light cell craft,
00:53:48calling on his fellow scientists
00:53:49to keep an open mind
00:53:51about its origins.
00:53:53What sort of alien technology
00:53:55are astronomers searching for right now?
00:53:58Well, examples include
00:54:00artificial light,
00:54:01industrial pollution,
00:54:03or reflection of starlight
00:54:04from solar cells
00:54:06on the surface of planets
00:54:07around other stars,
00:54:09megastructures,
00:54:10or fleets of satellites.
00:54:13Space archaeology
00:54:15with our best telescopes
00:54:16might reveal technological equipment
00:54:18floating in space,
00:54:20similar to the two Voyager probes
00:54:23that we launched
00:54:24and are now leaving the solar system.
00:54:30But we should keep in mind
00:54:32that the travel time
00:54:34is very long between stars.
00:54:36It would take the Voyagers
00:54:38about 100,000 years
00:54:40to reach the nearest stars
00:54:41to our sun.
00:54:43The equipment could, therefore,
00:54:45be defunct
00:54:46if it belongs to a civilization
00:54:47that died by now.
00:55:01The artifacts we're most likely to find
00:55:04include the defunct debris
00:55:06of highly sophisticated technologies,
00:55:08which could be the wreckage
00:55:10of alien spaceships.
00:55:12Perhaps our best way
00:55:13to put our hands on them
00:55:14is to find objects
00:55:16that collide with Earth
00:55:17and survive as meteorites.
00:55:21Is the truth out there?
00:55:23When astronomers peer out
00:55:25into deep space
00:55:26in search of alien technology,
00:55:29they're often looking for big objects,
00:55:31such as a Dyson sphere,
00:55:33a theoretical Death Star-style space station
00:55:37built around a star
00:55:38to harvest its energy.
00:55:43A civilization capable
00:55:45of building a Dyson sphere
00:55:47would have to be highly advanced
00:55:49because it would take decades
00:55:51or even centuries
00:55:52to build such a structure.
00:55:58Jason T. Wright,
00:56:00Associate Professor of Astronomy
00:56:02and Astrophysics
00:56:03at Penn State University,
00:56:05became world-famous
00:56:06after speculating
00:56:08that the mysterious behavior
00:56:10of a distant sun
00:56:11called Tabby Star
00:56:12was caused by a megastructure
00:56:15moving in front of it,
00:56:17although this hypothesis
00:56:19has been dismissed.
00:56:21The idea that we should look
00:56:24scientifically for evidence
00:56:25of alien technology
00:56:27in the solar system
00:56:28goes back to Ronald Bracewell
00:56:30in 1960.
00:56:31Although, of course,
00:56:33people half-speculated
00:56:34about Martians
00:56:35and such for centuries,
00:56:36he said just 100 years ago
00:56:39it was totally reasonable
00:56:41for scientists to discuss
00:56:42the possibility
00:56:43of technological life on Mars.
00:56:46In the 60s,
00:56:47the Mariner probes
00:56:49showed that the Martian surface
00:56:50has no obvious signs
00:56:52of large technology,
00:56:53and so people assumed it
00:56:55and the rest of the solar system
00:56:57must not have any sort
00:56:58of technology on it at all.
00:57:03But no one has put
00:57:05scientific numbers
00:57:06to that assumption.
00:57:07How much of the solar system
00:57:09have we checked?
00:57:11Sure, we can rule out
00:57:13the existence of big cities
00:57:14on nearby planets,
00:57:16but what about smaller things?
00:57:17How long would something last
00:57:20on the surface
00:57:21before we would not recognize
00:57:23it as technological?
00:57:26The search for bigger structures
00:57:28out in space
00:57:29requires a different strategy.
00:57:31Finding artifacts
00:57:33outside the solar system
00:57:34is a whole different matter.
00:57:37In that case,
00:57:38we would not be looking
00:57:39at images of things,
00:57:41but perhaps for the heat
00:57:43it gives off,
00:57:44or its shadow
00:57:45as it passes
00:57:45in front of a star.
00:57:47These sorts of artifacts
00:57:48would have to be
00:57:49tremendously huge,
00:57:51bigger than Earth,
00:57:53for us to even notice them.
00:57:59Space is large,
00:58:01so if we find something
00:58:03around a star
00:58:041,000 light years away,
00:58:06our radio waves
00:58:07haven't even gotten
00:58:08to them yet.
00:58:09even if we do
00:58:10ever set up communication,
00:58:12it will be thousands
00:58:14of years between messages,
00:58:16so contact will be
00:58:17pretty limited and slow.
00:58:19However,
00:58:20Wright does believe
00:58:21that if we do find signs
00:58:23of an alien civilization,
00:58:25then it's probably
00:58:26still alive.
00:58:33On a cosmic timescale,
00:58:35things don't tend
00:58:36to last very long
00:58:38after their creators
00:58:39or maintainers go away.
00:58:41So what about the possibility
00:58:43of finding alien probes
00:58:45near the Earth?
00:58:46There's no reason
00:58:47to think that such probes
00:58:49couldn't be constructed,
00:58:50but you would have
00:58:51to build an enormous number
00:58:53of them for us
00:58:54to notice one flying
00:58:55through the solar system.
00:58:59There are hundreds
00:59:00of billions of stars
00:59:01in the galaxy,
00:59:03and if there are artifacts
00:59:04moving among those stars,
00:59:07they will spend most
00:59:08of their time
00:59:09in deep space
00:59:10where no one
00:59:11would ever notice them.
00:59:13For one to just happen
00:59:14to be passing
00:59:15through the solar system
00:59:17around now,
00:59:18there would have to be
00:59:19thousands of trillions
00:59:21of trillions of them
00:59:22throughout the galaxy.
00:59:25But sure, it's possible
00:59:26to build that many machines.
00:59:29If they are what are called
00:59:30von Neumann machines,
00:59:32Johnny von Neumann
00:59:34was a scientist
00:59:35who discussed
00:59:36the implications
00:59:36of building a machine
00:59:38that could build
00:59:39a copy of itself.
00:59:41If you build one of those
00:59:42in space on an asteroid,
00:59:44the idea goes
00:59:46that it would build
00:59:47a copy of itself,
00:59:48then those copies
00:59:49would build copies.
00:59:51Eventually,
00:59:51they'd run out
00:59:52of asteroids altogether
00:59:54and would have to move
00:59:55on to somewhere else.
00:59:57If they could go
00:59:58between stars,
01:00:00then at each star,
01:00:01they would turn
01:00:01all the asteroids
01:00:02into more copies.
01:00:04With a scheme like that,
01:00:06you could eventually
01:00:06have enough
01:00:07that would be everywhere.
01:00:09Despite our best efforts,
01:00:12humanity has so far
01:00:13failed to discover
01:00:14even the most basic form
01:00:17of alien life.
01:00:18Dr. Paul Davies,
01:00:20a professor at Arizona State
01:00:22University,
01:00:23is author of
01:00:24The Eerie Silence,
01:00:26Searching for Ourselves
01:00:27in the Universe.
01:00:29His book grapples
01:00:30with the Fermi Paradox,
01:00:32an argument which discusses
01:00:33the contradiction
01:00:34between the high likelihood
01:00:36that aliens live
01:00:37somewhere in the universe
01:00:39with humanity's inability
01:00:41to find them,
01:00:42which is often called
01:00:43the Great Silence.
01:00:46He has previously called
01:00:48for a search of the moon
01:00:49to look for traces of aliens,
01:00:51as well as discussing
01:00:52the possible existence
01:00:54of a shadow biosphere
01:00:56on Earth,
01:00:57populated by undiscovered
01:00:59creatures which behave
01:01:00very different to all
01:01:02other known forms
01:01:03of life on our planet.
01:01:14Searching for alien artifacts
01:01:16on the moon is possible.
01:01:18If there was alien technology
01:01:20in the solar system,
01:01:21this is a good place
01:01:22to look,
01:01:23because the lunar surface
01:01:25is relatively stable.
01:01:27We search right here
01:01:29on Earth for artifacts
01:01:30in the genomes
01:01:31of terrestrial organisms.
01:01:33This might be as simple
01:01:35as a message
01:01:36uploaded into the DNA sequence
01:01:38of a microbe.
01:01:39Human scientists
01:01:40now do this all the time.
01:01:42Or in the existence
01:01:44of a shadow biosphere,
01:01:46implanted here,
01:01:47say, 100 million years ago.
01:01:49However,
01:01:51there is a risk
01:01:52that we might not
01:01:53even recognize
01:01:54alien life or technology
01:01:56if we discovered it.
01:02:11from ancient artifacts
01:02:13to monuments
01:02:14and structures
01:02:15on our planet,
01:02:17as well as others,
01:02:18seem to suggest
01:02:20we are not alone
01:02:21and mankind
01:02:22has been visited
01:02:23and influenced
01:02:24by extraterrestrials.
01:02:26Perhaps one day
01:02:28we will be able
01:02:29to travel back in time
01:02:30and see where
01:02:31such structures
01:02:32and artifacts came from.
01:02:34But still then,
01:02:35we can only massage
01:02:37the science
01:02:38and try to understand
01:02:39the technologies
01:02:40that once existed
01:02:42or determine
01:02:43if they were inspired
01:02:45by someone else.
01:02:47We live in a wondrous world
01:02:50with mysteries
01:02:51and questions
01:02:52all over the globe.
01:02:54But when it comes down to it,
01:02:56the only real question
01:02:58is what do you believe?
01:03:00Did aliens inspire
01:03:02or even create
01:03:03some of the curious structures
01:03:05and artifacts
01:03:06we're continuously finding?
01:03:08Or is it man himself
01:03:10more intellectual
01:03:12than we have ever considered?
01:03:16The answer to our questions
01:03:18may not be in the stars,
01:03:20but rather right here
01:03:22on our own planet Earth.
01:03:27Here is what it looks like.
01:03:28Thank you.
01:03:50Thank you very much.
