The current trend of increasing atheism/agnostism seems to indicate this. You know what wouldn't surprise me, if scientology was a true world religion in a few hundered years.
Think about it, Christianity was original regarded as a dangerous wacko cult. At first it was Jesus (Hubbard), preaching a book, and after his death it became a religion which was regarded as bizzare and dangerous. However, 1500 years later and its one of the biggest religions on the globe.
And it caters for what we need now. Christianity was in context for the time, but this religion embraces space, aliens and the stress of modern day life.
Don't worry, I think its a pile of tump.
