What was the first continent to have civilization?

The first continent to have civilization is generally considered to be Asia, specifically in the region known as Mesopotamia, which is located between the Tigris and Euphrates rivers in modern-day Iraq. This area saw the rise of some of the earliest known civilizations, such as the Sumerians, around 3500 BCE. These early societies developed complex systems of writing, governance, and agriculture, laying the foundation for future civilizations.
