The prophecies that you and other skeptics say refute Jesus are just interpreted wrongly imo.
As for the way modern historians handle the prophecy of the Temple destruction, it is used to date the gospels to post 70 AD and I have seen it used that way, just as I have seen OT prophecies used in the same way to date the OT books.
A critical scholar would be remiss to ignore the prophecies, in the sense of not considering what was written to have any bearing on the dating of the books.
There is plenty of evidence for the early writing of the gospels however, including that Christians are said to have escaped Jerusalem because of the prophecy.
