I agree that such a thing would be hard to prove but I was more inclining to what Physics131 felt about such a thing to further understand his viewpoint on things and ,yea, that computer simulation needing to be bigger than the universe is wiiilld. Amazing how humanity can figure stuff like that out.

Your response reminds me of the Aurelian and Aristotle frame of seeing the divine and how the Aurelian philosophy clings more to the notion that God exists outside of the universe and how Aristotle clings more to the idea that Nothing cannot create Nothing so in some terms God is also a manifestation of existence and not God manifesting existence as per the Aurelian philosophy but both viewpoints are definitely worth exploring and learning from .
