It's actually much worse than that. Not only would whatever created it have to live in a universe that allowed some form of intelligence - which is unsatisfying, but not all that much worse than "big bangs happen"; not only does it need a creator, it needs a creator with a universe that is computationally far more powerful than our own. After all, the only way in which we can simulate physical phenomena well is by actually running the experiment. Sure, computer software is very helpful when building a plane, but we still need wind tunnels. I'm convinced that we will create more powerful computers, but I'm not aware of any claims that a particle can be used to accurately simulate two particles... or even one millionth of a particle. (Note that reality doesn't seem to have accumulated any rounding errors even after running for a couple billion of years.)
