Mesopotamia was primarily centered around the Tigris and Euphrates Rivers, which flow through modern-day Iraq and parts of Syria and Turkey. These rivers provided essential water resources for agriculture and supported one of the world's earliest civilizations, enabling the growth of cities like Babylon and Ur.
On the other hand, ancient Egypt was built along the banks of the Nile River, which is still found in present-day Egypt. The Nile was crucial for irrigation and farming, helping to sustain the civilization and allowing it to thrive for thousands of years.
