There is a long list of New Testament scholars, many traditionalists, some not, who place the Gospels in the 40-60AD range.
Afaik, the late dating really began in the 1800s, so the traditionalist view was early.
Yet even today, many hold to early NT dating.
And have the Gospels ahead of Acts and the Epistles and Revelation.
So your arguments are circular, in error and GIGO.
If you are going to make pedantic, condescending, one-sided arguments,
please at least have your basic facts right.
Thanks!
