The Caddos would be the closest to making cities in the area, but the people living around there date back over a thousand years these larger communities we might call towns were still mostly small enclaves that didn't last more than a few hundred years at the longest mostly. And they were mostly a pretty recent, being a few thousand years newer of a civilization than Greece et. al., as they appeared well after 1,000CE
Meanwhile Athens and what not can easily be seen as an actual city even 2000BCE.
