No, it's not an accident, and that's OK in the long and short run. After all, man is trying to describe something that he has few words for. Imagine a Neanderthal trying to describe an automobile. He would be hard pressed to simply understand the stylish interior much less the twin overhead cam engine. Can you imagine the petroglyph?It is not an accident that the Bible is replete with anthropomorphic nonsense.
So man tries to make sense out of God. Sometimes extrapolating and quite often interpolating his observations all the while trying to make some sense of them. It's inevitable that a certain amount of anthropomorphism would occur in doing this. Does that invalidate his perception/conclusion that some super natural being exists? Not at all.
