“Those who deny the Creator, sensing they need to fix the problem of cosmology caused by this denial, insult themselves further with the logically incoherent idea that ‘things created themselves.’”
That’s nonsense and you know it. Even Kant and Schopenhauer — and, yes, even Nietzsche — didn’t suggest such a thing. They — especially Nietzsche — had issues with the CHRISTIAN God; but none of them denied a source of creation.
You’re asserting philosophers are credible when they believe in the Creator.
