The three gospels of Mark, Matthew and Luke agree on some parts of the story. They were written withing three or four decades of the alleged time of Jesus.
Those three books are consistent in that Jesus was a human being who later became a god. When we get to the book of John the story changes. It is the Book of John that is most read.
By the time the Book of John was written, six decades after Jesus, churches had been meeting for generations. The majority being illiterate worshipers were read to at gatherings. We all know that when we read something out loud in front of people it flows differently than when we read silently. TV newscasters are skilled at writing for being read out loud.
It is logical to assume the same thing happened back then. Reading material like Mark and Matthew would have been altered over the years so it read better out loud. Edited thousands of times to make it more readable and entertaining it became the Book of John.
By the time that Book was entered into the Bible sweepstakes Jesus was no longer a man who became a god. He was a god who became a man. He was a more dramatic and had Trump-like personality. For some reason that made for a better storytelling. Maybe tastes had changed.
Because the Book of John is so out of sync with other parts of the Bible it is not regarded as history by critical scholars.
