On confidential upper levels, Scientology teaches that a powerful space alien named Xenu brought billions of people to Earth in DC-8-like spacecraft, stacked them around volcanoes and blew them up with hydrogen bombs.
It was like something out of a science fiction script - but L. Ron Hubbard, the founder of Scientology, claimed it was fact. "Xemu," he called the central character. Xemu ruled the 90-planet Galactic Confederation 75-million years ago, when overpopulation was a problem. So Xemu solved the problem: He trapped selected beings and flew them to volcanoes on Earth, then called Teegeeach. He then dropped powerful H-bombs on the volcanoes. The beings were destroyed in a wall of fire. However, their spirits, or "thetans," weren't. Gathering them into clusters, Xemu trapped the thetans in frozen alcohol and glycol.
Publication of secret documents that blame the world's troubles on an interplanetary tyrant named Xemu has held the Church of Scientology up to public ridicule. Church leaders vow to prevent further release of secret scriptures in ongoing courtroom battles with opponents the leaders say are attacking the Scientology religion. According to the tracts, Xemu, fighting galactic overpopulation, ordered humans and beings from other planets captured and placed in several large volcanoes.
Documents obtained by the Los Angeles Times show that members of the Church of Scientology believe that mankind's ills were caused by an evil ruler named Xemu who lived 75 million years ago. Scientologists have been trying to prevent the release of the documents, which they consider secret and sacred, and about 1500 church members crammed three floors of the Los Angeles County Courthouse, effectively blocking public access to documents.
