If you think about it, any religion that could be "proved", wouldn't then require faith.
No, I understand that. It's a basic premise of religious belief. My mother is a devout catholic. I was raised as a catholic. I understand Christian theology better than most self-proclaimed atheists. As with technology, I intensely dislike people who attack things they haven't taken the time to understand.
Now... I do not agree with it, but I will gladly go to war to defend your right to exercise your beliefs in peace and tranquility
or the natural (like Darwinism).
I don't have to believe in evolutionary theory. It does not require faith, so it's not a religion. I can look at the existing evidence and decide if I agree with the scientific methodology that produces its basic theoretical basis. I can challenge it if I have a differing conjecture or even conflicting evidence. Last time I looked the Vatican did not allow for any of that.
Still, I do not think it's appropriate to apply the scientific method to religious beliefs. That's just a clever cop-out tactic cooked up by people who are hostile to religion. Just don't tell me 'Darwinism' is a religion and we'll be OK
