The idea that, since a certain explanation appears to suffice, it must therefore be the truth, is an obvious fallacy.
Besides that, there are many people who disagree that it suffices to explain us.
Well, the GP was really just obliquely calling back to Occam's Razor. Evolution is a very simple process that explains biological complexity, compared to creationism, which requires a sentient creator to have invented the universe wholesale.
Of course, Occam's razor should be treated as a guide... it's no proof.
Truth? No. Just a best guess based on evidence. And the people who disagree are free to provide more evidence in favor of their contention.

That is a most excellent explanation.
The best argument for evolution isn't a listing of how badly-designed we are, it's a simple observation that the one simple principle of natural selection through modified descent suffices to explain us. We don't need any other hypothesis. Therefore, the principle of parsimony kicks in and other, more complicated, hypotheses are ruled out. Not absolutely, but fairly strongly, at least until we find things that our current hypothesis cannot explain, which hasn't happened yet.
