===Archaean Eon===
*'''4 to 2.5 billion years ago'''
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.
