Watch this:
Benjamin Sommer is a Jewish scholar. He speaks about Jews believing, before Maimonides, that YHWH had Fluidity of Divine Selfness and Multiplicity of Bodies. I just started reading the book, but it seems that Ancient Israel at one point and Christianity have an ancient near eastern view of the nature of a god, that YHWH could fragment himself into Avatars (with the pagans one god fragmenting into many idols at the same time, with the idols becoming a living incarnation of that god, while the god still existed in the spirit realm simultaneously), making them God and having a God because they still had individual personalities, while the rest of him still existed in the heavens. For instance, the way Jesus as being God but also not being God seems similar to how the Gods of the near East could become one with each other but also individuals at the same time. The idea is foreign to the west as we are influenced by the Greeks view of the nature of God which is a God can only be at one place at a time and cannot fragment with the consciousness of that God being present in each fragment.
When the Bible refers to YHWH being the only true God, while all other gods are impotent idols, the Bible is saying that the pagan gods are not real because their idols are not incarnations of that god. They are lifeless. And they therefore cannot do anything.
I could be wrong because I am just starting to study this understanding of God and gods, but it is fascinating. When it comes to God we try to rationalize the unknown, which we cannot fathom, and then get into arguments about it.
If this understanding of the nature of God in the Bible is actually what the bible is saying, then pointing out that Jesus had a God, had a father, that the father was greater than him, etc, is irrelevant, as the man Jesus was an Avatar for YHWH. He was a fragment of God incarnated into human flesh.
