Belief in God, or gods, requires magical thinking. When it comes to things we can see and touch, science has mostly supplanted magical thinking, even to an understanding of the concept of the self, which formerly was thought of as the soul, whether mortal or immortal. There is still room to posit a cosmic clock-winder outside of space and time, containing everything within it, in some sense. That would be the omnipotent, omnipresent and omniscient God of Christian theology. Germanic and Nordic people believed that at gotterdammerung, all the gods died and went to hell, which was a very cold place. That bleak vision was replaced, sometimes at sword point, by the rosy promise of an eternity in heaven, the Christian promise. That's all pretty simple, as it has to be for most people to grasp it.

Thanks for your replies.
