god is a thing that exists outside of this dimension which i have theorized to be the catalyst behind the big bang, i.e. it caused two membrane universes to collide producing a third membrane which is our universe.

other than that, i dont think it does much. maybe it caused that first single celled organism to form on earth, maybe it threw that big rock that killed the dinosaurs, but thats about it. Basically it's like a kid with an ant farm.

"Cool! Look What they did today!" That basically sums it up.
