Is it truly that case that a universe without God, meaning the god of classical theism, is truly the simplest explanation? While it seems true that the god hypothesis posit one extra being, it also seems that the lack of some transcendent explanation for being itself leaves being itself unexplained. Now maybe being itself consitutes a brute fact, as Russell thought. Personally, I consider that tack special pleading. And I am not saying that is your position. My only point is that while I agree that parsimonious explanations are to be preferred, the application of Occam's razor involves more than just counting entities. William of Occam certainly never applied it to his own belief in God. That alone should give one pause.
