History
Long ago, the Annunaki had seeded Mars and Tiamat with life. Eventually, advanced cultures emerged on the two planets. More than 100 millions years ago, the two cultures fought for unknown reasons. While Mars was turned into a wasteland, Tiamat was utterly destroyed, and its remains became the Asteroid Belt. The Annunaki mourned for eons over the loss of the two civilizations.[2]
