Are you trying to argue that archeological texts weren't written by humans? Because otherwise I don't understand how your comment is related to the parent comment. It has nothing to do with not knowing the identity of the author. It's about the author being a human.

I’m arguing they’re minds of unknowable foreignness to our own. We fill in the gaps because the text per se has meaning. If anything, we give those minds meaning through the text, not the other way around.
We impute “the thoughts that produced” those writings. One can just as easily contemplate the method through which human writing got distilled into a matrix of numbers that produced a particular output in response to a prompt.
(I’ve absolutely read works without a care in the world for the author.)
