I have a quibble with that. I don't think they had evolved the capacity to have that feeling of pride in possession, or even any concept of "ultra-modern" and "cutting edge". That idea has been rising since the first set of people evolved to a point where they didn't require a herd mentality or large group of people to survive. They became so powerful and adapted that they eventually started wanting to smaller communities. With those communities comes conflict and the first real divide in humans as a whole. These communities were in competition and hoarded land, food and supplies. Lots of stuff happens I'm too high to write out in between. Then you get to times like the Egyptians and different empires and intelligence because they're not totally reliant on purely survival, so their mind evolves into other aveneus of development. People start to have an ego. They want to be distinguished. Lots more happens that we all know about and we get to a more modernish era. It, for a while, is actually a more socialist view of stuff. People want their own communities, countries, to have more wealth, not just themselves. Now a more modern time, and after more inter communal conflict over borders. That gets resolved. There's another conflict over borders and ideologies. Resolved. You know what, I'm kinda high and I have it all figured out but this has taken way too long to type.

Basically in the times of cavemen they would have seen the cave as nothing but survival. They were prototype people basically, and only had the functions to know shelter is good. I think people think that they were super advanced because of Hollywood movies and such. They really were as simple as it gets in terms of a human conscious.
