Ancient Egypt

Ancient Egypt (c. 3100 BCE – 30 BCE) was one of history's longest-lasting civilizations — 3,000 years of continuous cultural, artistic, and intellectual development along the Nile. Its achievements are extraordinary: the Great Pyramid (the largest stone structure ever built), a writing system (hieroglyphics), advanced medicine, mathematics, astronomy, and administration governing 3–7 million people. Egyptian civilization was defined by the Nile — its annual flood deposited rich silt that made agriculture possible in desert. The pharaoh was considered a god-king, intermediary between humanity and the divine. The mummification of the dead (belief in physical resurrection), the Book of the Dead, and the elaborate funerary complexes of the Valley of the Kings reflect a civilization deeply focused on immortality.
