I recently read an article of ancient Egyptian culture, and was amazed by the great pyramids.
The pharaoh of each city was obviously considered very important, and also thought to be a god rather than a human, by the people. Pyramids seemed to have tied religion and technology together. They had a very ritualistic religion, which involved the sacrificial killing of royal people when the pharaoh died, and then burying them inside the pyramid/tomb. Technologically, it is apparent that the ancient people had and established system of measurement and very good understanding of geometry.
One can an make and inference that religion may have made the Egyptians build the colossal pyramids. However, I am wondering if people have any other opinions on why the great pyramids were built. And, why they Egyptians stopped building the pyramids after the first 500 years of their history.
