I'm sure Maxis has an explanation for all of this.
One day millions (billions) of years ago before Earth existed, God was playing on his Atari 1 (yes thats even before any other thing was invented) and he was playing The Soms City, which is much alike the Sims and SimCity combined, yet in this game you create the world.
So God did this, and we are all a part of his game. And Jesus was a leetzor hack that he found to get his belief increased (sort of like Miracles in Black & White) but right about now Belief in God as christians know it, is quite bloody low.
So he better find that leetzor hack again or else hes fucked. Because anyone whose ever played B&W (2) knows that when a God has no belief he gets the shove.
Cheers
