"So many centuries, so many times
We were the prisoners of our own fantasy
But then we had nothing to lead our life
No, no, we can't live without Gods."
From Blind Guardian's song "Valhalla." It's a pretty true quote by itself! Some people really can't (or don't realize they can't) live without some kind of god because they feel like they would be lost without it. Either that or they'd prefer not to entertain such a possibility!
