Egypt was known anciently as KEME, which means literary black Land referring to the rich black soil on both Sides of the Nile. because the Nile was flooding because of rains at its source far to the south in Ethiopia leaving silt (sediments) on its banks and made that part fertile land.
The Nile was not only just the cause and inspiration of ancient Egyptian culture, it was also the unifying thread running through Egyptian history. therefore It witnessed royal progresses, the transport of Obelisks, the processions of gods,besides that the Nile helped the movements of armies.
Egypt was divided into two parts: Upper Egypt (south) and Lower Egypt (north) because the Nile flows from south to north that’s why they are named this way.
