or maybe He creates new realities and new universes because he likes some mortal person's idea so much. Lets say someone suggested a world where karma was far more obvious. If God favored this idea would he then experiment with a reality where everyone accepted karma as fact?
I'm not saying he would change our reality but possible alternate realities. There's really no limit to how many he could create. Maybe that's our purpose, to see what concepts and ideas other beings come up with outside of God's mind.
I think there already are an infinite amount of realities in parallel universes..every possibility already exists we just havent observed them yet and I supposed it could have been a god that created them all
