You don't understand how historians evaluate historicity, frankly.
We're aware that Biblical "historians" have operated in this manner, but you should know that these "techniques" for evaluating historicity are unique to the field Biblical history, and it's a known problem with the field. It's why so-called "Biblical scholarship" has produced basically nothing of note.
When techniques of
actual historians are applied to the Bible, it's impossible to connect them to any "autograph."
