	Things calm down and cool off, with vulcanism slowly declining. The soup of toxic volcanic gasses cools off, resulting in massive rainstorms which fill up the oceans. From this churning chemical soup heated by geothermal vents emerge organic chemicals, some of which form into complex structures and some of which begin to replicate. Eventually these basic molecular replicators give rise to the earliest life-forms, simple single celled creatures floating about in the ocean that concentrated around geothermal vents and floated about consuming whatever bits of useful chemicals they stumbled across.

The first plants begin to show up on land in swamps and gradually begin to turn muddy swamps and eventually dry deserts green. Atmospheric oxygen levels rise significantly, briefly triggering another ice age. Arthropods begin to crawl onto land, combing the beaches and latter nibbling on early land plants.

	At this point, some single cell develops a capacity to use sunlight to make sugar from carbon dioxide and water. This gives them an edge over those cells which just float around for whatever bit of odd chemical energy they can scrounge up and they fill the seas with these Cyanobacteria. They change the atmosphere, filling it with oxygen and eventually cause a massive ice age. This was a set back, but life slowly continued to refine itself in this period. Things such as sex evolves at this time as well as the first multicellular life emerges. Though these are simple things such as slime-molds and sponges.

This gives them an edge over those cells which just float around for whatever bit of odd chemical energy they can scrounge up and they fill the seas with these Cyanobacteria. They change the atmosphere, filling it with oxygen and eventually cause a massive ice age that nearly wipes out life on Earth before it could really get started. This was a set back, but life slowly continued to refine itself in this period. Things such as sex evolves at this time as well as the first multicellular life emerges.
