Well, as the "church" of Scientology was founded by a third-rate, science fiction writer, and they pretend that they are all related to a supreme person called Xemu, I would have thought that flying saucers were an entirely predictable thing to be seen flying over the HQ.
You know, its often said that you couldn't make this sort of thing up, but as far as Scientologists go, that is exactly what they did !

All religions are made up and Scientology is no exception. Best ignored is my opinion.
