Liz, space shuttles exist. God, on the other hand.... I may be missing something, though, as I don't see where "sharing" comes from.

Julian, I don't see anyone defending religion, just pointing out that people do have a God-shaped hole. I find it plausible that that hole exists, and personally I'd like to plug it to the extent that I have one, but only if I was confident that doing so wouldn't reduce my feeling of transcendent awe at real things.
