I'm well aware of these. And yes, lots of areas around North America had quite complicated and developed societies with large trade networks and even "highways" connecting ancient cities. But, these things are practically entirely disconnected to the societies of people living in the US today. And that's the point I'm making, this area is very young in terms of what is here now. That some other group developed something like a city several hundred miles away thousands of years before this town existed has effectively zero impact on the development of this place and the lives of the people who live here. This isn't necessarily the same for cities that have existed for hundreds or thousands of years which still even has some of the same streets and buildings of history. You'd be hard pressed to find a single structure still used here today that was older than 1940 in this town outside of a few notable rare examples dating back to the 1920s, that's a closer example to my point. What's the age of the oldest building in Paris? How about London? Athens? Trier? These are places that have had a practically uninterrupted flow of people living in dense urban places for many hundreds to thousands of years. This is just not true for massive parts of the US. Few cities draw their roots back to even the 1500s, with many having their roots go to the 1800s or even newer.
