Civilisation can only begin when there is enough prosperity to provide a surplus of produce to divert after providing subsistence. The river valleys were fertile and well watered enough to produce this surplus.
The ancient age, often referred to as ancient history, is generally considered to have started around 3000 BCE with the advent of writing and the establishment of early civilizations, such as those in Mesopotamia and Egypt. This period typically ends around 500 CE, marked by the fall of the Western Roman Empire. However, the exact dates can vary based on regional histories and the criteria used to define the era.

Ancient people began settling the Nile River valley around 5000 BCE during the Neolithic period. The fertile soil, consistent water supply, and natural resources of the Nile made it an attractive place for early civilizations to establish settlements and develop agricultural societies.
The environment provided a surplus of food so resources could be diverted from just surviving to more advanced culture.
