Thanks much for your informed reply.
This is anecdotal, but I’m old and have followed these things for a long time. I think the age of these things, writing and civilization and religious culture, has been continually discovered to be older and older and older.
The more we learn, the further back it goes.
It, seems to me, that once it was put into writing, it was meticulously preserving in text (while simultaneously preserving language and religion and culture).
Of course we cannot know the, likely much more lengthy, oral chain; but, I believe, we can attribute a very similar adherence to the original there.
We are looking at a very very long time of unbroken transmission of history and beliefs. The more we learn the further back it goes.
I think 10,000 years is a conservative estimate. And that can be difficult to grasp and understand the content.
Certainly in the case of Jews, or even Catholics, the first historical indication or proof of acceptance of a text or even belief is always generations, hundreds of years or more, after it was widely accepted. Modern scholars like to pretend that isn’t really the case.
