Thank you for your most informative post. I had studied much of that long ago but unfortunately the knowledge has long since “flown the coop.” In any event, the salient point is that there is no reason to dogmatically insist that the Israelites could not have possessed a form of writing prior to C10 BC. There is, as you suggest, every reason to believe that they had written language from their earliest history.
You’re welcome.
Agreed on the salient point.
