And if the prophecies revolved around someone rising from the dead after three days, and you saw them rise, and wrote about it, THAT would NOT be an eyewitness account?
They were written some 35-40 (gospel of Mark), 50-60 (Matthew’s and Luke’s) and 60-75 years later (John’s).
But needs I reminds you that these names (Mark, Matthew, Luke and John) are not names of the actual authors to these 4 gospels. Those gospels were written anonymously, and no where near contemporary to the events of Jesus’ birth and Jesus’ ministry.
Those 4 names attached to the those 4 gospels respectively, are the real authors, because no one know who really wrote them. But the names we see attached to these 4 gospels, were given by the the 2nd century church, were really attributes, not the authors.
I used these names as matter of convenience, to distinguish one gospel from the others, but in no way do I think they were written by the names given.
Anyway, I don’t any of these were eyewitnesses’ accounts and definitely weren’t contemporary to the events as narrated.
Your errors are assuming they were written by the men traditionally claimed and accepted from the 2nd century church. The people you assumed to be “Matthew” and “John” to be Jesus’ apostles and to be authors, then why were these 2 gospels written so far later, and not shortly after Jesus’ death and alleged witnesses.
You mentioned death and resurrection event, and while all 4 gospels stated Mary Magdalene was there, the first ones to reach the tomb, whether she went there alone (in John 20), or with 1 (Matthew 28 mentioned “the other Mary”) or with 2 companions (Mark 16 says Mary mother of James and Salome, while Luke 20 says Joanne and Mary mother of James were Magdalene’s companions), they are not in agreement.
And that in gospels of Matthew and Luke, they spoke to all 11 surviving apostles, or only to Peter and unnamed disciple in John. And there 2 versions to Mark 16:8, the short version say they spoke to the 11 disciples, but the original verse says they informed no one because of their fear.
These conflicting details, tells me, that none of these authors were there at the time. And if these John and Matthew were really apostles and authors, then why is that minor details showed they are not in agreement?
And the conception-birth story from gospels of Matthew and Luke, which demonstrated the discrepancies of 2 sources, not only of each other, but with general timeline.
Neither authors could have been eyewitnesses, so they must be the authors’ inventions.
