Ancient Advanced Technology in South America

There are a host of ancient ruins in South America, claimed by the Inca, inherited by the Inca, conquered by the Inca and built by the Inca. Although one label has stuck on each monument or ancient site, it is clear there are many layers of construction, physically and conceptually. Academics and Scholars still debate who built these, monuments, did they inherit them. Was there a Pre-Inca culture, but everyone can appreciate how advanced the 'Inca Ancient Ruins' found in the highlands of South America. The Inca were largest empire ever seen in the Americas and the largest in the world at that time, yet doubt is cast on their monuments and origins. Tiahuanaco, a region of Bolivia that holds many remnants of ancient civilizations, demonstrates some of the most unique and amazingly precise examples of stonework in the world. The ancient people who created these walls and buildings used such a high degree of mathematical expertise that the workmanship is astounding even to modern day people. They marvel at how the stone-cutters from long ago created all of it with simple hand tools.
