Yesterday in the National Museum in Reggio Calabria I found myself wondering how a people from 7500-8000 years ago came up with geometric shapes to decorate their earthenware with. @mrundkvist
My guess is that there is no way to find out. And by find out I mean propose an interpretation that everyone accepts and which is then never successfully challenged.
One of my core tenets as an prehistorian is "Assume that it's unknowable until you're forced to abandon that idea". I am not a friend of untethered speculation.
