The mysterious structures of Pumapunku, high in the mountains of western Bolivia are believed to date to around 536 AD, the Inca believe it is where the world was originally created.
It was part of a greater complex belonging to the Tiwanaku culture that predates the Inca's by many years.
Some stones are from a quarry located about 90 kilometers away near Lake Titicaca, it is unknown how they were transported such a great distance as the largest stone is 131 tons.
The stone blocks are cut perfectly and fit precisely with astounding accuracy without the use of mortar, it is said the joins are so tight that a piece of paper could not fit between them. The best example are the 'H-blocks' which display a polished and machine like quality.
An effigy depicted on the structure known as the 'gateway of the sun' certainly does not look human and local legend talks of superhuman beings using soundwaves to lift the stones in air.
There are many other examples of precision stonework in ancient South America and many depictions of alien like beings and even spaceships in artwork and carvings but the site at Pumupunku is possibly the most compelling example of advanced ancient civilisations existing on our planet many years ago.
