What country did Greek historian Herodotus dub "the gift of the Nile"?

The Greek historian Herodotus famously called Egypt "the gift of the Nile" because Egyptian civilization depended entirely on the Nile River's annual floods, which deposited fertile silt across the desert landscape. Without the Nile, Egypt would be entirely barren desert. The Nile provided water, fertile soil, and transportation for ancient Egyptian civilization.
