I fully agree with this paragraph and the one that follows this one but the OT, as a whole, is a, seemingly divinely inspired, collection of myth, creative nonfiction and stories from other cultures. The Book of Proverbs is a good example, as it is almost entirely composed of the same things taught to the sons of the Pharaoh, and the story of Noah and the flood is the tale of Gilgamesh. The important thing the OT does is recognize that there is but One God, and create a religion of monotheism. And for that, The Hebrews/Jews should get credit (at being the chosen vehicle, not for being a 'special' tribe or 'special' group of people).

As you say, God had to start sharing his message somewhere, so why not with the Hebrews, the tribe of 'many peoples'? Other cultures of the time worshipped multiple, or countless 'gods', but Abraham was able to express that there is, and by definition can only be, a single God, one True God.
