What developed along the upper inel verri aroung the same time that civilization arose?

Along the upper river valleys of regions like the Tigris and Euphrates, the Indus, and the Nile, early agricultural societies developed around the same time civilization arose. These areas saw the emergence of farming, leading to surplus food production, which allowed populations to grow and form complex societies. This agricultural foundation facilitated the development of cities, trade networks, and centralized governance, marking the dawn of civilization. Additionally, innovations in writing and technology emerged, further advancing these early societies.
