Africa may have given rise to the first human beings, and Egypt probably gave rise to the first great civilizations, which continue to fascinate modern societies across the globe nearly 5,000 years later. From the Library and Lighthouse of Alexandria to the Great Pyramid at Giza, the Ancient Egyptians produced several wonders of the world, revolutionized architecture and construction, created some of the world's first systems of mathematics and medicine, and established language and art that spread across the known world. With world-famous leaders like King Tut and Cleopatra, it's no wonder that today's world has so many Egyptologists.
