1st thought envoking question of the year

This Intellectual thought invoking question comes from my son Dylan. How'd he get so smart?
So we are re-modeling our upstairs bathroom right now. This has entailed removing the tile flooring and wallpaper from the walls. I of course took the toilet off the floor and it is temporarily in the bath tub. So Dylan comes in and wants to help me. We began to rip the wallpaper off of the wall! Side note, this is a lot of fun to do with a 4 year old! So anyway, Dylan notices the hole in the floor where a toilet used to be. As his questions pursue I explain to him that the hole is where his poop goes when he flushes the toilet. Of course that is not enough info so I then have to explain that the pipe carries the poop underground to place with a big tank that gets all the poop and pee and keeps it there. (before you start going off on me in your head about how they process the poop and everything remember I am talking to a 4 year old). That seems to be enough info and he is quiet for a while. Then he turns to me and asks "Where does God's poop go?" I could only answer with, "That's a good question. I don't really know. Maybe rain is God peeing on us!"
So that is the Thought Invoking question of the year. "Wear does God poop?" I hope some scholar reads this and leaves an answer to this question in the comments.
