The laws of physics are way too messed up for someone to not have thought them up.
Unless, the most messed up part about the laws of physics is that no one thought them up.
Mindfuck.
Well, that is considering if this is all existence as we know it. In that case, it's pretty well managed. But what if there truly is an infinite number of universes? With an infinite number of possibilities? Then it would be inevitable to have quite a number of universes in which the constants are just right. It would also be inevitable that there are universes in which even though the constants are different, it still works properly.
