Answer:
The first civilizations were developed in the fertile valleys such as the valleys of the Euphrates and Tigris rivers, because they allowed them to develop agriculture.
Step-by-step explanation:

As the population grew and the specialization of work and social division intensified, the first urban centers were formed, where families lived who were not directly linked to food production.
