There's a slight "paradox", for lack of a better word. Imagine tomorrow you die, only to 'wake up' and discover it actually was just a simulation. And you're now in some new reality. Well it turns out you haven't really answered anything, because the exact same question still remains of what's the source of this new reality. Turtles all the way down? And I expect there is probably no answer, because there's quite disconcerting little issue of first existence. Even if you imagine that the matter for a big bang could just materialize out of some weird quantum fluctuation, then you're left to wonder about what created the void, or what created the rules as they exist. You end up with this sort of uncomfortable hand-wavey, well it's just always been this way forever. Even increasingly abstract things like multi-verses don't really manage to reconcile this. If you think about it enough, it's really quite uncomfortable than "we" (whoever "we" may be) actually exist given this paradox. Because it's a question that intelligent existence may actually never be able to answer, and only testable by the experiment from which nobody returns.
