Phat, Phat, Phat. It's not a matter of what I believe rather it is a conclusion based on the Evidence and reality.
All of the material in the Bible shows classic signs of human origin and all of the material in any particular Canon was selected solely by Humans and all of the different Canons include different collections of material and all of the different Canons are equally valid.
What does the actual evidence show rather than what do the Apologists sell?
