The same way if you arrived in Greece during the roman period you'd have 2000 year old temples to look at and if you go there now you have both the 4000 year old ones and the 2000 year old ones.

That's what I said. There have been multiple. The linked article is about the Aquiry civilization which numbered 3 million people in only 3% of the land. The Marajoara outlasted them. The Upano Valley civilization predates both of them by 100 years and built dense garden cities. The Beni Mounds spanned over 20k earthen mounds and human-made forest islands that were connected by massive canals and causeways
