There is no way that the Fourth Gospel was written by John Zebedee or by any of the disciples of Jesus. The author of this book is not a single individual, but is at least three different writers/editors, who did their layered work over a period of 25 to 30 years.
Many of the characters who appear in the pages of the Fourth Gospel are literary creations of its author and were never intended to be understood as real people, who actually lived in history.
