“One also finds, even to this day, some amazing works such as the aforementioned Sachsayhuaman and the Coricancha in Cusco, where no mortar of any kind was used. It was stone-on-stone, with astonishing accuracy of fit. In the Inca toolkit, as found in the archaeological record, only copper and bronze chisels have been found, along with wooden measuring instruments and stone pounders or hammers. Conventional archaeologists contend that such tools were responsible for the refined workmanship seen in Cusco and other 'Inca' areas. However, the stone used - granite, andesite, and basalt - are harder than the majority of the tools used, and thus could not have been responsible for the work. The same is true of Tiwanaku and the connected site of Puma Punku. Massive megalithic blocks with sculpted surfaces are found at these locations, made of local sandstone, which would be difficult to shape with bronze chisels and stone hammers. However, the real enigmas are the even harder andesite and basalt stones, cut and shaped with such precision that modern engineers, stone masons, and other professionals question how such work could have been achieved without at least 20th century technology.”
