Okay here is the story.
Some galacting king named Xenu ruled the Galactic Federation. One day the galaxy became overcrowded so he froze aliens, stocked them on jets, sent them to earth, and melted them in volcanoes. The alien's spirits came up but Xenu used soul catchers and forced them to watch a movie about earth's "fake" history, and sent them off to find human hosts.
