However you define “silly”, It’s going to be hard to beat the space alien soap opera .

The evil alien ruler Xenu killed millions of aliens (Thetans) from around the universe by kidnapping them, bringing them to earth in golden DC-8 “space-planes”, stacking them around volcanoes & blowing them up by dropping “h-bombs” into the volcanoes. Scientologists believe the souls of these aliens (these souls are “Body Thetans”) were captured, brainwashed & released; they then attached themselves to our ancestors (and according to Scientology’s belief in Thetan immortality, they also attached to us during “past lives”) & cause many of our mental & physical ills to this day

South Park provided a nice summary Using L Ron’s own words so there is no doubt.

I was wondering where the Conservative right wings came from as I never found their pod. This explains it all.

Voting for Mormonism over Scientology? Huh?

I know I’m biased, but still.
