Well you are in a way, what is a simulation ? It's just a set of rules you follow that are simpler than the more complex environment that it runs in: I suppose if we could "see" "outside" the "universe", we'd understand that maybe our reality is very simple and limited compared to the "reality" outside. Maybe this would be true infinitely, or maybe the outside reality would be much more logical than ours, and we'd accept it's finite.

But since we have a beginning, and a flow of time, we probably also have a birth, a mother, and maybe even a purpose... but that's a very human way to think, might all just be random soup.

But imagine there's a self-aware agent in a simulation we create, he starts thinking the same thoughts, everyone mock him "we're all just random, there is no God, no design, how could so much energy be spent on such a useless giant block of empty space for any reason", he would have to sort of agree, but he would be sort of wrong. And discovering us, would bring him no solace: we can't tell him of our own designers ourselves. Discovering them, would bring us no solace either, for the same reason. That's why the concept of God is stupid: God has a God too, so what do we do now, solved no problem to accept His existence.
