I know racism is cathartic, but ignorance is not. Just because you know a big word like na-dene doesn't make you smarter or superior to them. Although knowing a thing's name in order to obtain power over it is a fixture of eastern mysticism dating back to the edge of pre-history.
Let's try to turn a shitpoll into something more interesting. Some caveman facts:
-people or broadly hominids never lived in caves for the reason that they are damp, dark and quite frankly there are better places to live.
-cave people are still people, like you and I and they aimed to spend the least effort for the most gain in whatever they did. The pyramids? Built by a volunteer labour force of several thousand in return for food, booze and shelter. Their irrigation system was far more grande.
-when hiking through the wilds of your locale look for a rock overhang typically under sandstone cliffs overlooking the landscape and neighbouring running water. This is where the indigenous people of your land likely resided.
-they also liked to live anywhere nice next to a big river and overlooking plains where game migrated. You might be familiar with such places as London, Paris, Moscow, as well as others
-there is virtually no evidence Neanderthals or even morphologically modern humans did cave art until about 20-17k before now. Thereafter cave art seems to appear globally. It's a fascinating mystery and seems to do with an emergence of a religion, spread through migration and cultural exchange
-the hunter-gather economic model places severe restrictions on population. As soon as one society encounters one that can produce more people is as soon as that society disappears.
-on the other hand imagine if you were able to hold the sum of your society's knowledge in your head. We're talking everything, technology, literature, medicine etc. That's approximately the reality of being a hunter-gatherer from a mental perspective.
