Incorrect. Buddhism is the most popular religion in Asia, and has no concept of a personal God.<quoted text>
..There have been "No Atheist" societies or civilizations in past known human history.
People have had different concepts of God, but one one thing they all agreed, that God created every thing in this universe.
As you point out different cultures in the past have different religions and different gods. This is solid proof there is no God. Cause if there was a personal God, he would be inspiring people to believe the >same< thing. As all religions are contradictory, and supposed revelations inconsistent and highly contradictory, this proves there is no personal God.
