How did the #AncientCivilisations​ cut and shape such intricate stonework like we see in #AncientEgypt​? How were holes seemingly drilled through solid granite? How did the #Incas​ create walls with perfectly connecting blocks of stone? Did they use traditional tools? Did they harness the power of the sun as I explained in a previous video? Or did they know the secrets of sound and this was a form of ancient high technology?
