@STNGfan,
The Canon of the Bible is a fascinating subject
The oldest copy of any portion of the Bible is the Gospel of Mark dated to 125 CE (almost 100 years after the crucifixion), it was likewise 50 years after Israel's losing war with Rome.
That copy (the oldest gospel in existence) ends at chapter 18, making no mention of a resurrection. Later Gospels are found in their origin from 150-170 CE with the canonization occurring somewhere around 200 CE.
Given those dates it is mathematical impossibility that they were actually written by the men they were named after. In fact if you look closely at the writers of that period they make no mention of it. Even early Christian writings don't refer to the Gospels until 150 CE.
There is one account of a historian who claims around 150 CE that the Gospels were in fact written by the men they are named after but it's actually a Roman Priest in 350CE writing about how this man 200 years earlier made this claim.
No independent evidence supporting the Catholic Priests claims has ever surfaced. And while there is no evidence to lay claim that he fabricated this we all know the Roman Catholic Church wasn't above fabrication to support it's agenda.
All your non-canon gospels were written between 150CE and 250CE, but they were left out as most of them didn't favor the Pistic Christianity that Rome wanted to install...
