00:00Where did all the water on Earth come from?

00:03It's a question that sounds simple,

00:05until you realise the answer stretches beyond our planet,

00:08beyond our sun, and straight into the bones of the universe itself.

00:12Because here's the plot twist.

00:14Earth wasn't born with oceans.

00:17In its early days, our world was a glowing sphere of molten rock.

00:21Any water that touched it instantly vaporised.

00:24Seas, lakes, rain, none of it existed.

00:27Yet today, our planet is drowning in over a billion trillion litres of it.

00:33So where did this impossible flood come from?

00:37Part of the answer lies deep in space.

00:40Billions of years ago, icy asteroids and comets,

00:44dirty snowballs travelling thousands of kilometres per second,

00:48bombarded the young Earth.

00:50Every impact delivered frozen water and hydrogen,

00:53like cosmic cargo ships unloading oceans.

00:55The rest came from inside the planet itself.

00:59Earth's interior held trapped hydrogen and oxygen.

01:03As volcanic eruptions tore through the crust,

01:06those gases met, formed water vapour,

01:08and rained back down, relentlessly.

01:11So every wave, every raindrop,

01:14every glass you drink,

01:15has been on a journey since before Earth existed.

01:19You're not drinking water.

01:21You're drinking stardust that learned to flow.
