I am happy to entertain real scholarship and real science. The comparatively few tools and fossils evident prior to 4000BC are widely scattered, and far too few to conclusively declare that hunter/gatherer was the only societal form - Largely a presupposition that fits the preferred evolutionary model.
Farmland would necessarily be near to water. Rivers and streams meander over many centuries, and could wipe away evidence of 'towns' and farming. We see this in contemporary history, where evidence of known habitation is scoured away completely. You have no evidence to stand on.
Which is why I pointed directly to anthropology rather than archaeology.
