I have no real problem with religion provided it doesn't get in the way of spirituality...if that makes sense. Normally I don't discuss religion unless someone else brings it up. It often upsets people. If someone specifically asks me then I'll explain why I have a rational, naturalistic worldview.

Overall I think you're right- two hands working gets more done than two hands clasped in prayer. Even religious people allude to that in sayings like "the Lord helps those who help themselves." Faith could be a comfort during a survival ordeal, but then so could your knowledge of survival. In either case, fortune favors the prepared.
