There are so many megalithic constructions around the world that indicate some kind of an advanced ancient knowledge, in shaping, placing and constructing. It is seen in ancient Egypt at Giza, in Latin America at places like Puma Punku, Ollantaytambo, Machu Picchu, Cuzco, Saqsayhuaman and every as far out and remote in Easter Islands. I find this interesting and there are many speculative theories out there. But the best introduction for someone who still needs to learn that slaves did not build the pyramids, and that there were no tombs there – should see The Revelation Of The Pyramids. It’s a fantastic documentary with opinions by experts in construction, engineering and egyptology. The documentary is a must see for anyone interested in the topic. It goes through different theories and does an excellent job in showing the places and illustrating the information. Here are some screenshots I found interesting, also an image where I compare the drill hole in Puma Punku to a modern drill machine I took a photo of a while back.
