Good points. Yes, some truths can’t be empirically verified. One is free to postulate the existence of a god "outside of time and space," whatever that could possibly mean. But doing so is superfluous - there is nothing for that god to do. The model works just as well without that additional hypothesis.

Furthermore, as I said in my "Profoundly Challenging Questions to Ask an Atheist" blog, if one accepts the evidence for evolution (denying evolution is tantamount to a flat-earth claim) then a god who operates through evolution can only be thoroughly cruel or indifferent, not to mention inefficient, tinkering, and bungling, and certainly could not be all-powerful, all-knowing or all-good.

Moreover, in the twenty-first century we have a coherent evolutionary psychology understanding of why the human mind is cognitively biased to believe in gods and a purposeful universe in the first place. For a brief summary of just some of those reasons, see my blog "Why We Think That Everything Happens for a Reason," elaborated in my book.
