One thing I've seen is that Indigenous Australian oral history is thought to extend back at least 37,000 years[1]. Natural events that have been demonstrated to have happened tens of thousands of years ago have been passed down in the oral history of some civilizations. This knowledge conversely seems to be lost with a transfer to written records, probably due to a lack of people keeping mental note of ancient knowledge. e.g., a lot of Native American history is just lost for countless reasons, despite them having written records now.

Okay, fine, let's just believe whatever feels good to us.
- language is important?
- speaking predates writing?

This is the premise he implicitly asked for in order to voice his sentiment ... and you deny him even that without him listing a source (which is precisely the thing he was concerned with).
"I am saddened by all the violence" -> "take that back or I hit you"
Edit (slightly OT): let's not "all believe" in anything. We need to be able to allow contradictory things to coexist
In our society, you can just say whatever you want without backing it up in any way, and then get irritated when someone asks how you figure.
