The new testament stories were written well over a hundred years after
Not right.
These were written 20 to 30 years after: https://en.wikipedia.org/wiki/Paul_the_Apostle ("Fourteen of the 27 books in the New Testament have traditionally been attributed to Paul. Seven of the Pauline epistles are undisputed by scholars as being authentic, with varying degrees of argument about the remainder.") It would be more like someone writing about this now, which I do remember.
Gospel of Mark is dated to around the year 70
Book of Revelation around 81-96
The canonical gospels are the four which appear in the New Testament of the Bible. They were probably written between AD 66 and 110. — https://en.wikipedia.org/wiki/Gospel
The New Oxford Annotated Bible claims, "Scholars generally agree that the Gospels were written forty to sixty years after the death of Jesus. They thus do not present eyewitness or contemporary accounts of Jesus's life and teaching."https://en.wikipedia.org/wiki/New_Testament
