You seem to equate "belief" with "religion" in some classical religion sense. But strictly speaking, that's not quite accurate.
Most folks 'believe' that the cars zooming by the intersection will stop when their red light shows to them. Most folks believe that drunks will not run a red light and T-bone them.
Belief that there is no God is certainly also a belief. That belief also has it's origins and supporting hypotheses etc. etc. etc.
I'll stop there before Qx eggs me on into one of his major treatises.
Some people might say that. Me? I don't say nuffem. Just spitballin'.
I hereby retire from this conversation. Hereon. :)
