Massive stone wall built by hunter gatherers? That seems odd,
More like herder-gatherers. :^)
Yes odd but that the self-made paradigm they are stuck with. No one in today’s archaeology is allowed to have advanced further than hunter-gather at that time. They have the same problem with the far older structures at Gobekli-Tepi.
Odd? Yup, why would a hunter even put two rocks together? There went my BS flag on this story as it is so far?
