Aliens invade earth, hoping to kill all intelligent life forms and steal our resources. They underestimate our weaponry, leading to our hijacking of their mothership. Humans now have complete control of an expansive alien empire. The entire population of earth, exempt twenty forgotten people, board the mothership and leave. The twenty people survive and breed. The humans on the ship adapt to their environment, and over thousands of years evolve to what we would consider aliens. The story repeats, as the mothership finds a planet with resources: Earth.
