There are many historical facts not supported by scripture. In fact, most of the word history from that age is hearsay and opinion. We know of the lives of 12 Ceasars from Suetonius but what he wrote was stories told to him but some unidentified others, -- hearsay -- and his opinions. Same for nearly every piece of ancient history: Pliny, Eusebius, Josephus, -- name it.
“There are many historical facts not supported by scripture”
As you say ‘MOST’ are not but neither do we elevate Josephus or Pliny to the authority of Inspired Scripture or if there is disagreement between the secular historians and Scripture raise these writers to a position of superiority, do we?
