During the past 40 years, it seems that about every nationality in the Old World has claimed to have founded the first civilization in the Americas. The problem is chronology. By 3500 BC, there were folks in Peru and the Amazon Basin building pyramids and cities, plus preserving their loved ones as mummies. The Bilbo Mound and Circular Port in Savannah were begun around 3545 BC. The Watson Brake circular earthworks and mounds were constructed around 3450 BC.
