    Fermentation is just what happens when you accidentally leave stuff in a container that limits oxygen. It’s easy to make alcohol my accident. Then there’s also the fact than we don’t know how well connected the world was before writing. We know farming developed independently from studies of soil in lakes and whatnot but recipes are much harder to pin down as something invented independently.

    Not sure about the swords part but the Aztecs didn’t any.
