I try to think of religion less as "magic" and more as philosofy. I am an agnosthic, and I shift from being a believer and not constantly - I'm currently on one of my religious moods - and I belive that EVEN if some atheistic came around and proved that God does not exist and that what we see is all we have and that death is merely the end of consciousness, even then I would say "read the Bible". Or ask for churches to be kept as they are. Because it's not the whole magic behind it that matters. Who cares if Jesus really walked on water or not? What matters is the message. What we do. How we behave.
