When I read articles about interpreting prehistoric glyphs, rock art,
myths, and so forth, I always wonder what is the limit to what, we
as modern human beings, can really know? How can we really
know what a prehistoric person in a culture, environment, and
milieu that was quite different for ours was specifically trying to
portray?

Also, how that guess be turned into a testable hypothesis?

Yours,
