Oh come on... if it weren't for religion, where would all of those poor, emotionally insecure people who can't handle the rigors and realities of scientific discovery go to get their crutch / security blanket? I mean... come on - religion has done so much to advance the cause of human civilization in the face of oppression from scientific discovery. Oh wait.
The greatest day in the history of humanity will be the one where we collectively throw off the yoke of religious superstition and embrace the reality of our own temporary insignificance and learn to be at peace with the notion that all we have is today - and one another.
