Prehistoric Civilization Built By Giants

According to Inca legend, Lake Titicaca was revered as the location where the god Viracocha [Quetzalcoatl] created a race of giants and later, the first humans. The Inca maintained that the giants built Tiahuanaco and also many other cities and structures in the area. However, due to their great evil, Viracocha destroyed the giants in a world flood. This legend is still believed by the local Indian inhabitants to this day. The geoglyphs covering this area also exhibit extreme age. In areas where ice age sediment surrounding hills and mountains has been eroded by rain and wind, patterns carved into the bedrock underneath the sediment has been exposed, suggesting their creation sometime before the last glacial melt near the end of the Pleistocene era, c. 13,000 years ago. Early researchers speculated that Inca and pre-Inca farming techniques produced the anomalous patterns on the ground around Lake Titicaca, especially in the horizontal terracing found surrounding the lake itself. However, the altitude of the Bolivian high plain presents several problems with a farming related explanation for the majority of the geoglyphs in the region. At an average of 12,500 feet above sea level, most of the shapes and patterns are located in areas that have not been conducive for growing crops for the last 10,000 years. Their creation would have required an immense workforce laboring for hundreds of years in such thin air that altitude sickness was a real danger... literally, a super human effort. Additionally, recent high-resolution satellite images suggest that most of the features are characteristic of religious and ritualistic forms of pre-Incan art. They may even represent a sophisticated yet unknown form of communication.
