Is there a Scientology creation story?

Hey I'm doing a religion project and I need some more information on Scientology, we're supposed to find a creation story about it, what they believe in, their gods, and what happens at a gathering (like church Sunday at a Scientology church).
Update: Holy crap are you serious about the Xenu thing?

I only saw it on Wikipedia and I don't believe it that much, can you provide me with a link to confirm it?
Update 2: Update: Anyone got anything on the whole Xenu thing yet?
