The lack of originality is proof that God exists. First time I've heard that tbh.

I've heard it many times, but it also assumes that there aren't other ways to explain similarities, such as cultural cross-exchange of ideas (which happens prolifically even in the Bible, hence why Israel is supposed to avoid inter-marriage and the like), and the fact that most myths begin to explain observed phenomena, which itself tends to be very similar and repetitive. I personally think this is an extremely weak argument that is only compelling if you have already presupposed that God revealed himself and his revelations were bastardized by civilizations around the world. It's classic Confirmation Bias.
