Bible historians have worked to verify the history in the Bible and have done a good job. When it comes to verifying supernatural events it seems odd to demand that be by someone who does not believe
So just how are supernatural events verified. Certainly not in any scientific way so the only way i can see is confirmation bias
We are talking about Pantera being the biological father of Jesus aren't we? So that is a rumor started by Jews in maybe the late 1st or in the 2nd century and what evidence do you have to confirm the rumor other than a Roman soldier by that name who could have been in the country at the time.(a common name it seems).
Exactly the same evidence as you have for god dun it.
For sure? No, but the work of scholars has shown we have what is close to the original. The New Testament is better attested than most historical writings which we accept.
Again, without evidence all you have is confirmation bias
