"Now, if the Nile inclined to direct its current into this Arabian gulf, why should the latter not be silted up by it inside of twenty thousand years? In fact, I expect that it would be silted up inside of ten thousand years. Is it to be doubted, then, that in the ages before my birth a gulf even much greater than this should have been silted up by a river so great and so busy? As for Egypt, then, I credit those who say it, and myself very much believe it to be the case; for I have seen that Egypt projects into the sea beyond the neighboring land, and shells are exposed to view on the mountains, and things are coated with salt, so that even the pyramids show it, and the only sandy mountain in Egypt is that which is above Memphis;...." -- Herodotos, historian, ~430 B.C.
Noobs think the pyramids were built yesterday. Actually, it is obvious they are much older than popularly believed. Peru pyramids at Caral predate Egyptian pyramids at Saqqara and Giza. They are much larger and more sophisticated: Ancient Peru site older, much larger.
A Peruvian site previously reported as the oldest city in the Americas actually is a much larger complex of as many as 20 cities with huge pyramids and sunken plazas sprawled over three river valleys, researchers report.They found no evidence of military fortifications or weapons. But they did find cotton, fishing nets, and cocaine.
Construction started about 5,000 years ago — nearly 400 years before the first pyramid was built in Egypt — at a time when most people around the world were simple hunters and gatherers, a team from Northern Illinois University and Chicago's Field Museum reports in today's issue of the journal Nature.
The society and its people — known only as the Andeans — persisted in virtually the same form for 1,200 years before they were overrun by more warlike neighbors. That is the longest time any known ancient civilization survived, according to archaeologist Jonathan Haas of the Field, who led the expedition.
The results greatly expand understanding of how complex states began in the Americas.
