I think this is an interesting question to ask.
Why do people choose to follow religions, or to create
religions?
And how deep is the belief? At some level does the person realise
that the religion is false?
For the purpose of this discussion, let's avoid Christianity, Islam
and Judaism.
Instead let us consider Jediism,

Where some people believe that George Lucus stumbled upon a
revealed truth, even if he doesn't realise it.
Or perhaps even Scientology which was created by Science Fiction
writer L. Ron Hubbard.
