I don't really have much to contribute on this topic, but here goes:

I'm an atheist that practices Wicca. I believe that belief is a tool and that there is a difference, a big one, between orthodoxy and orthopraxy. The placebo effect goes a long way, I find.

Now, that doesn't really speak to the topic at hand, but I think it's the same as making a topic called "Alchemy VS Chemistry". The same scientific method that put planes in the sky is the same that indicated that evolution via natural selection is true. 2 and 2 equal 4.
