Yes, Scientology was "created". I have a friend that went into Christian studies and gave me a paper once that had "How to refute Scientology" with like 3 points on it. One was a quote from Hubbard. One was a quote from his books. And the other was a picture of a document someone had written from inside "the system" I guess. I didn't quite understand it, but my religious zealot of a friend did.
But its nothing new. Lots of these cults exist to try and better people with false promises. Take the book "Stranger in a Strange World", by Heinlein. In it, he describes a church that has different levels of "knowing" or "groking" of each other, that ends up being a nested circle structure where in the innermost circles, sexual promiscuity is rampant. So then what happens after the book?

Or how about a religion that was started to get out of required college chapel services?

Solar Temple members tend to die off too fast to actually promote their religion.
