You might want to pull your pants up, for your ignorance is showing.
All of this information, comes from the NASB study Bible, which most universities use in their studies. So, it's a college textbook.
The Book of Matthew, was written by Matthew, as early as 50 AD, or as late as the 70s AD.
The Book of Mark, was written by John Mark, composed from the 50s or early 60s AD or as late as 70 AD.
The Book of Luke, was written by the Doctor Luke, as was the Acts of the Apostles. The commonly suggested periods for writing is 59-63 AD. Acts was written in 63 AD.
The Book of John, was written by John the disciple. And was written perhaps as early as the 50's AD and no later than 70 AD. OR(there are 2 separate views regarding this Gospel), around 85 AD, the first view is what recent Bible scholars believe.
The Book of Revelation, written by John, and most scholars date the book at 95AD.
The latest books of the Bible I could find would be dated around 105AD, a far cry from 150 AD.
Matthew and John both knew Jesus, Luke may have heard Him, but there is no account of him ever meeting Jesus, firsthand, and Mark was a close friends of Peter's, it is not told when the 2 met or if Mark ever met or even saw Jesus.
Now, you can argue all you want, but this is what is taught in universities all over the world.
By the way, you just got schooled, playa!
