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,
http://www.thejediismway.org/index.htmlWhere 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.
