Egypt is one of the most populous countries in Africa. The vast majority of its estimated 78 million people (2007) live near the banks of the Nile River (about 40,000 km² or 15,450 sq miles) where the only arable agricultural land is found. Large areas of land form part of the Sahara Desert and are sparsely inhabited. Around half of Egypt's residents live in urban areas, with the majority spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.

Egypt is famous for its ancient civilization and some of the world's most famous monuments, including the Pyramids and the Great Sphinx; the southern city of Luxor contains a particularly large number of ancient artifacts such as the Karnak Temple and the Valley of the Kings. Today, Egypt is widely regarded as an important political and cultural centre of the Middle East.

History
The Nile Valley has been a site of continuous human habitation since at least the Paleolithic era. Traces of these early peoples appear in the form of artifacts and rock carvings along the terraces of the Nile and in the desert oases. In the 10th millennium BC, a grain-grinding culture using the earliest type of sickle blades had been replaced by another culture of hunter-gatherers and fishers using stone tools. Climate changes and/or overgrazing around 8000 BC began to desiccate the pastoral lands of Egypt, eventually forming the Sahara. Early tribal peoples migrated to the Nile River where they developed a settled agricultural economy and more centralized society.

By about 6000 BC, organized agriculture and large building construction had appeared in the Nile Valley. During the Neolithic, several predynastic cultures developed independently in Upper and Lower Egypt. The Badarian culture and the successor Naqada series are generally regarded as precursors to Dynastic Egyptian civilization. The earliest known Lower Egyptian site, Merimda, predates the Badarian by about seven hundred years. Contemporaneous Lower Egyptian communities coexisted with their southern counterparts for more than two thousand years, remaining somewhat culturally separate, but maintaining frequent contact through trade. The earliest known evidence of Egyptian hieroglyphic inscriptions appear during the predynastic period on Naqada III pottery vessels, dated to about 3200 BC.
