Agreed. But when you have people who absolutely refuse to listen to (and accept) indisputable facts based on historical or scientific truths, a debate isn't even remotely possible. And a lot of the refusal to listen is based on discomfort and fear of change. They don't even have a legitimate "side". These people don't even belong in the debate. And as far as "theories" go......c'mon man, religion is nothing more than a "theory", with very little in actual fact (other than the actual existence of Jesus, Muhammad, Buddha, et al) to back it up. Yet billions world wide eat it up like candy. If you're into philosophy, our whole existence can be explained as nothing more than a "theory". We can play the "theory" game into infinity......
