It's certainly possible that our existence is the result of one or more ancestor simulations. My personal cracked-out theory is that time and space are both infinite, and thus computation is infinite. As such, our observable universe may be the result of an infinite number of ancestor simulations. Another facet of that theory which I enjoy pondering is the notion that the supernatural may exist (souls, ghosts, reincarnation, etc)—just in a simulation layer that exists above our own, but one that is still tied to our physical universe. Inaccessible but real. A more grim yet equally interesting twist on that would be the supernatural existing within our current physical universe, quantifiable and ultimately accessible (some day), but presently not yet discovered by science. Often all things supernatural or spiritual have a sense of morality imposed upon them, but I imagine such a finding would strongly suggest that the supernatural, if it existed, would be just as uncaring and cold as the physical universe, since it would itself part of the physical universe.
