The personifications of "God" come from religious myths, which you're supposed to be rejecting. If God" is a mystical placeholder for the mystery of the first cause of the universe, it adds nothing to saying that we're insignificant in relation to the whole universe itself or to the unfathomable quantum conditions of the Big Bang.

If you think "God" adds something to pantheism or to naturalism, you must be basing your view of God on the Bible, which means you're not opposed to religion as such. The Bible was formed by branches of Judaism and Christianity, which are religions.

So your worldview is incoherent (once again) or you're assuming a nonstandard notion of "religion."

Are you familiar with HP Lovecraft's cosmicist fiction? It exposes the existential sense in which we're nothing in relation to the cosmos. See also Thomas Nagel's book "The View from Nowhere," which makes the same point about objectivity. When we detach from our personal preoccupations and look at life and the universe objectively, we seem insignificant, so we have to reconcile that perspective with the subjective one, according to which we matter.

I've been writing about all of that for years and years. Your Americanized, anthropocentric Christianity has nothing to teach me about humility or about the existential crisis of realizing that it's the Scientific Revolution that truly showed our cosmic irrelevance.
