My friend wants to become a Scientologist--Is this real life?

So my friend wants to get into Scientology. I looked up the background story and it blows my mind with what these people believe in. Does anyone know a Scientologist?

The Story of Xenu

quote:

---

Once upon a time, 75 million years ago, there was an alien
galactic ruler named Xenu. Xenu was in charge of all the
planets in this part of the galaxy, including Earth, which in
those days was called Teegeeack.
Xenu had a problem. All 76 planets of the Galactic Confederation
he controlled were overpopulated. Each planet
had on average 178 billion people. He wanted to get rid of
this overpopulation, and he had a plan.
With the help of renegades, Xenu defeated his opponents,
the good people and their Loyal Officers. Then with the
help of psychiatrists and the media he persuaded billions of
people to come in for income tax audits. They were instead
injected in the lungs with alcohol and glycol to paralyze
them. Then they were put into spaceships that looked
exactly like DC-8 airplanes, except they had rocket engines
instead of propellers.
These space planes then flew to planet Earth where the
hundreds of billions of paralyzed people were stacked
around the bases of volcanoes. H-bombs were lowered into
the volcanoes, and Xenu detonated all the H-bombs at
once, killing everyone
