Is God a simulation?

At the end of my previous post I said

"...in order to determine whether our Universe is a simulation either we must leave this Universe, or the Super programmer must enter it. I'm quite certain the former is not possible and can say nothing about the latter..."

Having thought about it a bit I believe I can, after all, say something about the latter; i.e. whether or not not the Super-programmer can enter our universe, and I believe the answer is "yes". Since we are, by definition, part of his universe he should be able to interact with us.

As an analogy, think about the popular Sims games. In these games the user control their characters' actions. But when not being controlled the characters (the Sims) seem to have a mind and personality of their own and can basically go about living their own lives. They will sleep, eat, go to work, wash, go out with friends, even die. In short, they pretty much live a "normal" life in their universe. The only difference between the Sims universe and the one we live in is a quantitative one: number of sims, complexity of the sims, the "artificial intelligence" of the sims, etc. Fast forward 50 years when our computers are 33 million times as powerful as they are today. How much more complex a "universe" do you think we can create?

As for the programmer interacting with the Sims? That's easy. You "inject" whatever you want to say into the Sim's "consciousness" (ever read "Conversations with God"?), or you create an "angel" to deliver your message. Or you locally change (or disable) the laws of physics to enable some event to happen - in short you create "miracles" for your Sims.

Perhaps the feeling

Life would be so much easier if only I had the source code.

isn't that far off base.

The only thing I don't like about this scenario is that it begs the question: Is the Super-programmer's universe in turn a simulation? And if so, how many layers of simulations are there? Is there, ultimately, a "real" universe? Who or what create that? Or does it, like fractals, go infinitely deep?

The mind boggles. Is this any harder to believe that the simple answer: "God created the Universe"?
