All you’ve proven is that you haven’t engaged with the scholarly arguments for historical Jesus at all. A bunch of them are not kind to a fundamentalist position. For example, there’s an argument that the census story around Jesus’ birth is a fabrication–there’s no evidence for a Roman census around that time, and why would everyone need to travel to their birth town for this?–but the fact that they’re sticking it there is because they had to deal with Jesus being an actual guy from Nazareth. They really, really want to attach him to King David by having him be born in Bethlehem, and him coming from Nazareth gets in the way of that. So they create this whole weird census story to make up for it.

No matter if you agree with this take or not, it’s clear no fundie would come up with that or accept it.
