The Christians had fled to the hills (as Jesus had told them to do), and the Jews were killed hiding in the Temple, so not many were left to tell the story. You have to read Josephus to see what really happened!

You ignored the whole of his post for one little tidbit...everyone flees when a battle is raging in your neighborhood. So 100 lb hail stones fell when? When did 1/3rd of the earth’s fresh water get poisoned? When did the seas turn to blood and all the fish die? When did the 2 witnesses get killed by the beast and then get resurrected 3 days and 3 nights later...when did God say to them, “come up hither”? Theses are very specific prophecies not symbolism!
In what book of the Bible would one find Josephus' account ? ...
so much for the facade of Sola Scriptura among Evangelical and Reformed Preterists ...
