"As one ascends further into the levels of Scientology, new doctrinal points are revealed. A variety of problems afflicting the human race are explained as caused by an event that took place 75 million years ago. Humanity lives in an illusion that is due to a long chain of events ultimately traceable back to a cosmic cataclysm caused by the ruler of our local part of the universe, an entity named Xenu. These esoteric doctrines are clearly influenced by science fiction themes of contemporary popular culture."
