On proof, there is a good bit a proof supporting the big bang theory and the theory of evolution. There is a little bit of evidence supporting human evolution, though there is also a little bit of evidence supporting the bible (Such as the prophecies in the bible that have come true, Bible code
http://www.bible-codes.org/what-are-Bible-codes.htm , etc.). Both require a good amount of faith to believe.
However, my point is that religion, at least Christianity, is in no way evil. The majority of charities are Christian charities. For centuries, churches have organized all kinds of humanitarian efforts. Stuff like the crusades are not supported by the bible, and are very minor compared to all the good Christianity has done. To say all religion is evil is nothing more than bigotry.
