The advanced Egyptians
Whatever mystical, occult or science-fiction tales may be associated with the Great Pyramid, it is still an extraordinary piece of masonry, and its designers must have been extraordinary beings. Who they were and when they built their Pyramid remains a mystery. So the quest continues.
The history of Egypt is a long trek across the waterless expanse over the Sahara desert. Once you get started there is no turning back. Who for the life of them would dare to revise what has long been held true. But certain views are held as facts and must be confronted and the textbooks amended.
The designer of the Great Pyramid knew many scientific facts that he built into the structure. He knew the circumference of the earth the the precise number of lunar cycles in a year, the hours in a day, the precise seasons, and most remarkably the relationship of the earth to the precession of the Equinox.
They knew the varying lengths of a degree of latitude and longitude at different locations on the planet and could make excellent maps, projecting them with a minimum of distortion. They worked out a sophisticated system of measures based on the earth's rotation on its axis which produced the cubit.
Mathematics so advanced, they were not invented or re-discovered till millenia later: Pi, the Fibonacci series, and the golden ratio. We have just scratched the surface of what this past civilization knew, and the more we find a much longer history of man than before was credited.
