I've seen Peruvian skulls and they are not just deformed, they have anomalies which are unknown. When I showed the photographs to a Brazilian surgeon specialist in neurosurgery he just couldn't answer the riddle. I said to him there's a research done by a Polish guy suggesting they altered the morphology of the brain to mimic the lack of SULCUS division as Einstein's brain, so I suggested the ancients did have a whole team of Einsteins who also plugged in with 3D reality via hallucinogenic stuff. What he outta research is WHAT WOULD THE BRAIN WOULD BE INSIDE BEING PUSHED TO THE BACK LIKE MAYANS AND INCAS and the combo of using substances with pentexil ring or Ayahuasca and SAN PEDRO cactus used in Peru which even dilates the eyes and let people see at night like felines. Meditation and certain diet enhance the use of endorphines, serotonin and so on. The purpose was also seeing other dimensions. He needs to research the ancient people POLISHED THE STONES TO OPTICAL DEGREE with such an effort for two main reasons:1) to avoid the passing of light enhancing production of melatonin (the word mela is related to darkness) and
2) with no mortar or pitch between the rocks TO CREATE A SHORT CIRCUIT in the whole temples made of stone and that's why they used mica in Mayan land (from Brazil!!!) or copper alloys in Peru.
BTW I'm Peruvian
