Why Yahweh? (Or Allah, or Zeus, etc.)

[John V]

Wrong. It has the same air to it as the OT i.e. "he will be born of a young woman".

I.e., a flesh and blood human.

Paul fails to mention Mary's name and the fact that it fulfilled a "prophecy", namely, that it was a virgin birth.

And?

Clearly, to a Christian this would seem incoherent, but to me it makes perfect sense because it aligns with all the other evidence to show Jesus wasn't human but a spirit, or more to the point, the Sun of God, the Light of the world whose reflection against water makes it seem like he can walk on water.

Er, you just said above that it has the same air as "he will be born of a young woman," which indicates a human, not a spirit.

This isn't incoherent to Christians specifically, it's just incoherent.
