I think it's actually one of the best ideas ever
Believing in what is Real, instead of some crap fiction-based religion. And atheist isn't a religion, it's just saying "I don't believe in god". You should really read some more pages of the site, instead of just reading ~2 paragraphs and the name
I suggest these pages:
the Tree of Knowledge
How the Church of Reality got started
"Does God exist?"
Original, more rude "Does God exist?"
