Our advantages come down to incremental improvement. Thog takes a rock and splits it into sharp af edges and now hes got a hand axe. Ogg takes another rock, splits it into sharp bits (or not) and uses sinue or twine to attach it to a stick. now they could have a number of different tools. Nog figures out they can tan hide using astringent plants they soaked and exposed the hide to and now theyve got primitive clothing. But most people... would struggle if they had to survive without all that technology. Cats... can survive off hunting birds and rodents. They do such a good job of it that theyve wiped out the 2nd most species on the planet aside from us. And keep in mind these are housecats not wild cats or strays. Itd be like some dude living in suburbia going to the mountains and killing everything with his bare hands or whatever tools he could cobble together from the materials he found there. Most people... would probably die of exposure, starvation or wild animals like bears and mountain lions if they tried that. We do as well as we do despite this because we improve generation after generation. Thats it. That's our advantage.
