I reminded them that even today with all of our modern technology we had no idea exactly how the Incas built their cities with stones sometimes weighi...ng several tons or how they placed them so precisely that there was no gap between them whatsoever. We didn’t know how Peru’s famed Nazca Lines were created or why. There has been a succession of theories about how the pyramids of Egypt were built.
