Egypt Was Not the "Gift of the Tigris"—That's Mesopotamia

The phrase "Gift of the Tigris" is incorrect for Egypt. Mesopotamia (modern Iraq) is the land between the Tigris and Euphrates rivers, where annual floods deposited fertile silt, enabling agriculture and civilization. Egypt is the "Gift of the Nile," as Herodotus noted, because the Nile's floods sustained its society. The two river civilizations are distinct.
