bread requires figuring out that ground up grain with water can be poured onto a rock heated up by fire and made into a tasty pancake thingy
a knife requires a sharp rock, a stick, and a bit of rope made out of tightly twisted plant fibers
i’m reasonably confident if i was thrown into a jungle i’d be able to DIY myself a basic knife within a day or two, perhaps even before getting mauled by wild animals. Bread though? Even with the foresight of knowing what i need i’d struggle. Rocks, sticks, and plants are pretty much everywhere. Where do i find wild grain??
