One of the interesting things that sticks out to me personally that lends credence to the idea that the Bible is just kind of a bunch of half-remembered stories all mashed together is Barabbas- the guy that Pontius Pilate supposedly pardoned instead of Jesus.
In some versions, Barabbas is given the first name "Jesus"
And "Barabbas" could potentially come from "bar abba" in Hebrew Aramaic (although Hebrew "ben av" or "ben aba" is not far off) meaning "son of the father"
He was imprisoned and sentenced to execution due to taking part in an insurrection against the Roman empire.
The two characters- "Jesus, son of the father, and sentenced to death for sedition" and "Jesus, son of God, sentenced to die for claiming to be king of the Jews" sound a hell of a lot like they're referring to the same dude to me.
That's either one of the biggest coincidences in all of history, or someone heard two different versions of the same story and mashed them together.
Or maybe it's just sort of a 1st century version of the saying that "one man's terrorist is another man's freedom-fighter."
