Secrets Of The Egyptian Pyramids

In Secrets Of The Egyptian Pyramids we see the amazing architecture used over 4,700 years ago to build the last standing wonder of the ancient world.The documentary with the help of pyramid experts and modern architects and engineers tells us whats known about the construction and purpose of the Pyramids.But many questions remain unanswered as to how these mega structures were built with such primitive techniques and tools.Also the similarity between techniques used in Giza on the pyramids are found on other ancient sites across the world such as Easter Island and Machu Picchu can this be just a huge coincidence ? Can we now after hundreds of years of study and speculation turn at least some of the theory's into facts ?
