What is the most abundant life in the Universe? That’s a bold question, considering we have yet to see undisputed proof that ET even exists. The only model we have, is on Earth. So let’s unpack that, and see what we end up with.   Earth, 4.6 billion years old. That’s our scale. The scale has already been split into four eons.   The first eon is called Hadean. That first eon, lasted from 4.57 billion to 4.1 billion years ago. At 4.53 billion years, a mars sized object hit the earth, forming the moon. At 4.1 to 3.8, water and organic material begin falling to Earth.   It would be during this eon 4.0-2.8 billion years ago, where life on Earth took a foothold, the Archean eon. They were single celled creatures including microscopic microfossils.   At 3.6 billion years, we can see the emergence of cyanobacteria. These little guys begin to produce oxygen in Earths’ great oxygenation event.   2.5 billion years ago, Earths oxygen level begins to significantly rise.   Notice that Earth is almost half as old as it is n
