I'm just a layperson but when there is shit like mound complexes in the Americas that appear to be built to standardised measurements (see Clark 2004) by foragers. Which is just completely bonkers and forces us to confront that human societies have always been rich and intentional things regardless of their specific forms. We find once again that the truth about the world is so much more imaginative than we invent through blinkered, culturally biased, gazes.
