Unraveling the Age of the Egyptian Pyramids

The Egyptian pyramids were built between approximately 2700 B.C. and 1500 B.C., making them around 4,700 to 3,500 years old. The first pyramid was built by Pharaoh Djoser, and the last pyramid built for a pharaoh was constructed for Ahmose I. The pyramids were likely built for protection against tomb robbers and for religious reasons, possibly related to the growing influence of the sun cult. The construction of pyramids ceased, and pharaohs were buried in underground tombs in the Valley of the Kings, possibly due to security concerns.
