00:004.5 billion years ago, Earth was born. And it was hell. Not the world you know. No breathable air,
00:10no stable solid surface like today. The young Earth was battered by giant asteroids. Volcanoes raged, the surface melted again
00:19and again, and the sky was choked with toxic gas.
00:23But it wasn't just a ball of lava forever. Ancient crystals tell us liquid water, maybe even oceans, existed far
00:31earlier than we once thought. Then, about 4.5 billion years ago, the unthinkable happened. A planet-sized body, roughly
00:41the size of Mars, which we call Theia, slammed into Earth.
00:45The impact was so powerful, it vaporized enormous amounts of rock and blasted debris into orbit. And from that destruction,
00:54our moon was born. The debris circled Earth, clumped together, and became the moon we see today. Earth cooled, its
01:03crust hardened, and hell finally ended.
