Here is another story about myths being extremely persistent: https://www.economist.com/science-and-technology/2020/02/27/... Amazing if true. I got the impression, when I studied (a little) anthropology in the 1990s, that myths were related to the present structure of a society more than to its past, and that you couldn't expect reliable transmission of messages over such long time periods. Edit: here is a cool arti…
Jung, amongst others, believed that myths are archetypal constructs that underpin the architecture of the mind, and are shared by all, which explains much about the uncanny cultural similarities across time and space.
Frist candidate for an explanation:
* Stories get passed on and some are surprisingly stable.
Second candidate for an explanation:
* The underpinnings of the architecture of the mind cause the same stories to (re?)surface everywhere.
Let's use occams razor.
(I don't claim this argument disproves the "theory" of archetypes. But we should not jump to conclusions when applying it out of context.).
