I've been to Cahokia, and look forward to revisiting it in future decades since only 10% has been excavated so far!

44,000 years of continuous human occupation. (Except for a brief period during the 20th century ..)

A few years ago I made a graphic showing the years before present dates of some of the earliest archaeological sites across the Americas for Wikipedia: https://en.wikipedia.org/wiki/Peopling_of_the_Americas https://en.wikipedia.org/wiki/Alternatives_to_the_Clovis_Fir...
Also if one expands it to the Americas more broadly it goes back pretty far. Earlier this year on a trip to Central America I stayed in a home that dated to the mid-16th century. Still not as impressive as what Europe has, but was neat!
