thank youuuu

You're welcome.

The Sumerians, who lived in Mesopotamia (modern-day Iraq) around 4500 BCE, are credited with creating the first known civilization in human history. They made significant contributions to early civilization in several areas:

1. Writing System: The Sumerians developed one of the earliest known writing systems called cuneiform. It enabled them to record information such as laws, literature, and historical events. This system greatly influenced later writing systems in the region.

2. City-States: The Sumerians built several city-states, such as Ur, Uruk, and Eridu. These urban centers were not merely settlements but organized political entities with their own governments, religious institutions, and social structures. This concept of city-states laid the groundwork for later civilizations.

3. Agriculture and Irrigation: The Sumerians developed advanced agricultural techniques, including the use of irrigation systems. They constructed canals, dikes, and reservoirs to control and manage water flow, which allowed for more efficient farming and increased crop yields. This agricultural surplus supported the growth of Sumerian society.

4. Mathematics and Astronomy: The Sumerians made advancements in mathematics and astronomy. They developed a numeric system based on the number 60 that influenced the concept of counting and measuring. Additionally, their observations of the stars and celestial bodies laid the foundation for later astronomical studies.

5. Legal System: The Sumerians established a complex legal system that included written laws, judges, and courts. This legal system provided a framework for resolving disputes, protecting property rights, and maintaining social order. It influenced subsequent legal systems in the ancient Near East.

These are just a few examples of the contributions made by the Sumerians. Their innovations and achievements laid the foundation for later civilizations in Mesopotamia and beyond.
