Life, Part 1 (The Beginning)

It all began with an explosion. Particles flew out across a rapidly expanding universe. They found and combined with other particles, to make elements and galaxies and stars. Rocks formed, and floated across the vast universe. Like the particles that formed them, they started clustering together into circle-like shapes, now known as planets. This story will focus on one of those planets. It is the only planet we call home. It is the pale blue dot, Earth. The planet we call home now is definitely not what it used to be. Every planet started as nothing but a giant rocky formation. The same goes for Earth, which, at the time, was a desolate, foggy land. Earth was also not quite as big as it is now. And it would never had been, if a planet called Theia had not violently collided with Earth, fusing with it. Millions of chunks of rocks were thrown out into space, some of those rocks taking a circular shape, and forming our moon. The moon was much closer to Earth than it is now when it formed, though there were other, seemingly more severe effects. Theia crashing into Earth could possibly have caused a giant ocean of lava to form, turning the once desolate Earth into a burning land of volcanoes and a ground spewing of lava. This, surprisingly, was the environment in which the very first cells formed, which would later go on to become what makes Earth so unique in this solar system. Life. Though life couldn't exist in this hellish environment, and it took years and years for a cooling process to begin. This would turn Earth's vast oceans of magma into cool water, and would also make way for small land formations across the planet. These land formations were very dry and desolate however, and Earth didn't have enough oxygen on land to support life. And this is where life begins. It all started underwater.
