Archaeologists have found mysterious stone circles built before the Egyptian pyramids

Using radiocarbon dating, the researchers determined that the structure was erected about 4,750 years ago, which falls within the late ceramic period of Andean archaeology. As noted by experts, this structure was built about a century before the pyramids in Egypt and almost at the same time as Stonehenge in the UK.

Scientists attribute the structure to an example of monumental megalithic architecture, with the find representing one of the earliest examples of such architecture in the Americas.
