Earth, at the dawn of its time was very different from the flourishing world we know today. The Hadean Eon captures Earth in its most volatile form; volcanic, inhospitable, and showered in debris from space. Hadeon Eon Span: 4.6 bya - 4bya Earth's closest neighboor, the Moon, had just been born from a catastrophic collision with Theia, a haywire planetoid, that struck Earth head-on, throwing off debris into space. Over time, this debris concentrated into the satellite we all know today. The oceans were another gift from space, brought to us by the ice inside of space rocks that showered the surface. And then something interesting happened... Microbes began to form in the seas, the first living things hosted by this planet.
