I think you bring up a very important point here. The Bible is both historical and divinely inspired. That’s the beauty of it. It really happened and we can go and visit the places mentioned and read outside sources concerning its historicity. In other words, reason does not conflict with the divinely inspired texts. Truth is truth, after all.
The Book of Mormon, on the other hand, can make no such claim. All of the evidence points the other direction. Reason dictates that there is no reason to believe that which it purports to be history because there is not a shred of evidence in its favor. As to its purported “divine” origin, all we have is the claim of one man. That’s it. Not very convincing to me.
