The colonization of Eteria
Humans had a very advanced civilization one million years ago, but they forecasted the final explosion of the external layer Sun that will occur in the next five thousand million years, reducing the Sun to a white dwarf and the Earth to ashes, and they fleed to less hot and more stable stars. However, there were too many humans, and only a minority could abandon the planet using the few inter-galactic ships. The remanent humans fought a really severe civil war that lead to the Stone Age. The fleeing humans settled in an Earth-like planet, founding Eteria. They had contact with very advanced alien civilization, and they began to sell human software, their most successful bussiness.
