Sister Joan, I think he started by writing science fiction. Then he went on to re-lable and market his fiction as a religion that required a lot of money to participate in. And enough fools bought into his fabrication.
However, yours is a legitimate faith, unlike Hubbard's. I suppose you could make some money off of it. Probably need some celebrities though to help you promote it. I hear that Katie Holmes is no longer into Scientology. Maybe she will be open to joining the First Church of the Blessed Evaporator.
