The article discusses the age of Tiahuanaco, a well-known archaeological site in Bolivia, and questions whether it can be considered the "Cradle of American Man." Tiahuanaco is believed to have been an important civilization that thrived between 1500 BC and 1200 AD. However, recent studies suggest that the site could be much older than previously thought.

Archaeologists have found evidence of ancient human activity in the area dating back to around 15,000 BC, which challenges the conventional timeframe. This has sparked a debate among experts about the true age of Tiahuanaco and its significance in the history of the Americas.

Proponents of the theory that Tiahuanaco is the "Cradle of American Man" argue that the site shows advanced architectural and engineering techniques, as well as a sophisticated understanding of astronomy and mathematics. They believe that Tiahuanaco was the center of a highly advanced civilization that influenced later cultures in the region.

However, skeptics argue that the older dates are not necessarily related to the construction of the monumental structures at Tiahuanaco. They believe that the site might have been continuously occupied over a long period, with different cultures adding to its structures and artifacts.

Ultimately, the true age of Tiahuanaco remains a topic of debate among archaeologists. More research and excavation are needed to determine its exact origins and the role it played in the development of the Americas.
