Spirituality

Spirituality and humanity - Beliefnet:

Spirituality is 'just' an evolved reward mechanism, in the same way that breathing is 'just' a way to stay alive. Spirituality came first as we see in cave paintings and archeological figurines. The shamans came later and figured out how to make a buck by selling people something they already had, created God to bottle it in, then tossed the bottle into heaven so nobody could look too closely at it.
