Hubbard wrote that Xenu was the ruler of a Galactic Confederacy 75 million years ago, which consisted of 26 stars and 76 planets including Earth, which was then known as "Teegeeack".[5][8][23] The planets were overpopulated, with an average population of 178 billion.[1][4][6] The Galactic Confederacy's civilization was comparable to our own, with aliens "walking around in clothes which looked very remarkably like the clothes they wear this very minute" and using cars, trains and boats looking exactly the same as those "circa 1950, 1960" on Earth.[24]

Xenu was about to be deposed from power, so he devised a plot to eliminate the excess population from his dominions. With the assistance of psychiatrists, he summoned billions[4][5] of his citizens together under the pretense of income tax inspections, then paralyzed them and froze them in a mixture of alcohol and glycol to capture their souls. The kidnapped populace was loaded into spacecraft for transport to the site of extermination, the planet of Teegeeack (Earth).[5] The appearance of these spacecraft would later be subconsciously expressed in the design of the Douglas DC-8, the only difference being: "the DC8 had fans, propellers on it and the space plane didn't".[21] When they had reached Teegeeack/Earth, the paralyzed citizens were unloaded around the bases of volcanoes across the planet.[5][8] Hydrogen bombs were then lowered into the volcanoes and detonated simultaneously.[8] Only a few aliens' physical bodies survived

I still don't get the Scientology references to this band...when did that come along?
