Puma Punku has fascinated me since first seeing pictures of the remains. The exacting nature of the stones blows my mind. Having worked in the metal fabrication and various other mold building and tool making trades makes me think that these stones were some how molded, not carved. How one would go about molding granite and other hard stones is the mystery to me. I do know that the current technologies can mold and create 3-D items with extreme precision, Baalbek and many other sites may have used similar technologies. Just because we can clack at our keyboards never convinced me that we are the greatest that ever existed on this planet or in the universe.
