If you are speaking of Jesus of Nazareth, you have not advanced one truth, scientific or otherwise, that disproves what you call “desert nomad mythology.”
For one who takes a refuge in what you call “science,” you have only advanced your own subjective mythology, leaving me wondering “where’s the beef?”
I did, but your choosing to stick with mythology and your continual refusal to adopt the same standards for evaluating it, as you seem to do so, while arguing against science, is something I cannot help you with.
For the inconsistency in the “moral message”, let me just take an example from the Bible: 1 Samuel 15:3. Children and infants are ordered to be slaughtered here. What’s the beef, as you would say?
