Pumapunku is interesting, but sadly does not prove the existence of ancient aliens.At the first time I did watch the ancient aliens tv-show, I thought it was a cool show. 95 % of those things are just a lot of BS. But I think some things by that show are the real thing, but not can prove those things. For example the Puma Punku
First up we have the blocks
Big very heavy lumps of rock shifted a long distance with stone age or bronze age technology isn't unique in ancient culture. The blocks at Pumapunku are no bigger than some of the blocks in the pyramids of Giza and smaller than some of the Stonehenge stones or the heads of the Moari on Easter Island. Now experimental archeology has proved in all three cases the rocks could have been moved and raised quite efficiently using simplistic technology such as log rollers or a simple sled, 'A' frames, ropes and muscle power; and often far less muscle power than you would think - once you get something big and heavy moving and over come its inertia keeping it moving is relatively easy)The largest of these stone blocks is 7.81 meters long, 5.17 meters wide, averages 1.07 meters thick, and is estimated to weigh about 131 metric tons. The second largest stone block found within the Pumapunku is 7.90 metres (25.9 feet) long, 2.50 metres (8 feet 2 inches) wide, and averages 1.86 metres (6 feet 1 inch) thick. Its weight has been estimated to be 85.21 metric tons. Both of these stone blocks are part of the Plataforma Lítica and composed of red sandstone.[5] Based upon detailed petrographic and chemical analyses of samples from both individual stones and known quarry sites, archaeologists concluded that these and other red sandstone blocks were transported up a steep incline from a quarry near Lake Titicaca roughly 10 kilometres (6.2 miles) away. Smaller andesite blocks that were used for stone facing and carvings came from quarries within the Copacabana Peninsula about 90 kilometres (56 miles) away from and across Lake Titicaca from the Pumapunku and the rest of the Tiwanaku Site
yup the builders were master masons, but again this is not proof that ET won the contract to build the place. The rock is sandstone, easy to carve and mold, and mortarless construction was honed to a fine art in South America, so by the time Pumapunku was built in around 500ad the builders had several millennia of experience in the technique to draw on. As for the mathematics of the construction its is nothing that could not have been achieved with years of experience and basic tools such as plumb lines, and set squares, all of which technologies mankind has been using since the early stoneage.In assembling the walls of Pumapunku, each stone was finely cut to interlock with the surrounding stones and the blocks fit together like a puzzle, forming load-bearing joints without the use of mortar. One common engineering technique involves cutting the top of the lower stone at a certain angle, and placing another stone on top of it which was cut at the same angle.[4] The precision with which these angles have been utilized to create flush joints is indicative of a highly sophisticated knowledge of stone-cutting and a thorough understanding of descriptive geometry.[6] Many of the joints are so precise that not even a razor blade will fit between the stones.[10] Much of the masonry is characterized by accurately cut rectilinear blocks of such uniformity that they could be interchanged for one another while maintaining a level surface and even joints. The blocks were so precisely cut as to suggest the possibility of prefabrication and mass production, technologies far in advance of the Tiwanaku’s Inca successors hundreds of years later.[9] Tiwanaku engineers were also adept at developing a civic infrastructure at this complex, constructing functional irrigation systems, hydraulic mechanisms, and waterproof sewage lines.
And as a personal note I do get a bit annoyed when the great achievements of our ancestors are dismissed as 'impossible' and their great works attributed to aliens. In my eyes it someway diminishes the humanity of us all
