Oldest known civilisation in the Americas had advanced technology

Peru
Caral is the oldest known civilisation to have existed in the whole of the American continent, let alone Peru.
At least 5,000 years ago this culture sprung up in the Supe Valley, around 140 miles north of the modern city of Lima.
But there is one problem – the inhabitants of Caral were so advanced in technological terms that their culture must go back much further.
Having spent the best part of a year in Peru, I am certain there are still ancient ruins to be found buried in the sands of western Peru, and most likely they will be thousands of years older than Caral.
