What may be the oldest urban site in the world has been unearthed in Peru.
"Archaeologists say the site, uncovered amid a complex of ruins known as Sechin Bajo, is a major discovery that could help reshape their understanding of the continent's pre-Columbian history."
"Carbon dating by a German and Peruvian excavation team indicates that the circular plaza is at least 5,500 years old, dating to about 3,500 BC, said Cesar Perez, an archaeologist at Peru's National Institute of Culture who supervised the dig."
"That would make it older than the Great Pyramid of Giza."
