Also back to the "we are born to believe in God" line of thinking...
If atheism is the natural way for humans, then why did it take so long for it to develop? Atheism is a relatively new invention. The natural course of life was for man to have God in his life (one way or another). Higher criticism is new. Atheism took a LONG time to develop. I'm not talking specific belief in God here. I'm talking about mans historically natural need for the spiritual.
