1 ene 1000000000 año aC - Earth is formed The Age of Rock Begins

Descripción:

Around 4.54 billion years ago (which I can't fit on the timeline) the Earth began to form. Over the course of 10-20 million years large fragments of dust and space debris clump together. At some point a bunch of meteors covered in ice and water crashed into Earth which helped give it a sort of atmosphere. Also at some point life evolved on Earth. But the life was unicellular microorganisms.
