Half of the "New Testament" was written by Paul, who never even met Jesus. Pure fiction.
All of that story is alleged to have happened post-crucifixtion.
Paul's conversion experience is discussed in both the Pauline epistles and in the Acts of the Apostles. According to both sources, Saul/Paul was not a follower of Jesus and did not know him before his crucifixion. The narrative of the Book of Acts suggests Paul's conversion occurred 4–7 years after the crucifixion of Jesus.
