If there were only ONE living God there would not be need of a name because a name distinguishes and differentiates one from another of a kind.
The Old Testament is a strange and mythical world. It is an admixture of history and mystery and accretions of legend, myth, and perhaps absorption of Homer's epic tales of Odysseus.
