Look at the bible as a pastiche, a collection of mutually and often internally inconsistent fragments slapped together for crude reasons of politics and art and priestly self-promotion and sometimes beauty and a lot of chest-thumping tribalism, and through that lens, it makes a lot of sense. It does tell us something important…about us, not some fantastic mythological being. It tells us that we are fractious, arrogant, scrappy people who sometimes accomplish great things and more often cause grief and pain to one another. We want to be special in a universe that is uncaring and cold, and in which the nature of our existence is a transient flicker, so we invent these strange stories of grand beginnings, like every orphan dreaming that they are the children of kings who will one day ride up on a white horse and take them away to a beautiful palace and a rich and healthy family that will love them forever. We are not princes of the earth, we are the descendants of worms, and any nobility must be earned.
