Does not apply. There is no evidence for this other then an illiterate people who used oral traditions to communicate. Its a given.
So let's say there are all these collective memories about Jesus floating around: whose memories are those that are basically winning the battle of survival of the fittest?
Popularity won the day. Not the fittest.
"When" is the question, not whose.
What you are suggesting is an oral tradition that is very different than the example you compare it to:
I am not comparing it to anything. I am showing the capabilities of oral traditions. Not comparing traditions.
Why would anyone bother remembering this one obscure baptism among all the hundreds?
People talked about him at Passover, "did you hear he was from" "he was baptized by John" "I heard he said this" and so on. No mystery here.
Their newspaper was oral traditions.
Still by the 70s or 80s when Mark wrote the Gospels, it was important for Jesus to be baptized by John?
Not important, a detail about the man they followed that was important to them. His earthly history was important, even if still embarrassing that John baptized him.
There is no reason to list such a detail for the Hellenistic movement. There was no reason to hold a peasant Galilean teacher as the one, but they did, because those are the cards they were handed.
By that time, Jesus was the pre-existent co-creator of the world
Mistake.
The movement was wide and diverse and not everyone thought this. His divinity early on by Mark was not equal with god. His divinity was compared to the living Emperors divinity.
Mythology grows, it evolves with time.
we find exactly what we would expect if there were no oral tradition at the time of Paul and that Mark just made up his Gospel.
Not what we find.
We see evidence of a compilation of multiple source, and one source was oral traditions early on.
If an event was witnessed, your saying only written traditions in an oral culture could pass on history, how much sense does that make?
They were oral people, of course there were oral traditions. This movement did not start from a published book that was passed on. No book was needed for oral traditions to exist.
