What are the similarities and differences between the Sumer and Egypt River Valley Civilizations?

Similarities:

1. Both civilizations developed around major river valleys - Sumer developed around the Tigris and Euphrates rivers in Mesopotamia (modern-day Iraq) and Egypt developed around the Nile river.
2. Both civilizations relied heavily on agriculture for their economies. They developed advanced techniques for farming and irrigation to maximize crop production.
3. Both civilizations developed complex social and political structures. They had similar hierarchies with rulers, priests, and a social elite at the top, followed by a middle class of artisans and merchants, and a large lower class of peasants and laborers.
4. Both civilizations were polytheistic and developed complex religious beliefs and rituals. They built temples and practiced religious ceremonies to honor their gods.
5. They both developed systems of writing - Sumerians created cuneiform script on clay tablets and Egyptians developed hieroglyphics on papyrus.

Differences:
1. Geography: While both civilizations developed around river valleys, the geography of the two regions was quite different. Sumer was located in a flat, arid plain, while Egypt had fertile land due to the annual flooding of the Nile. This difference in geography influenced their farming techniques and overall economic systems.
2. Government and leadership: Sumer was divided into a number of independent city-states, each with its own ruler, while Egypt was united under a centralized Pharaoh who had absolute power. This difference in governance led to different political systems and levels of centralization.
3. Afterlife beliefs: The Egyptians had a strong belief in the afterlife and the necessity of preserving the body through mummification, while the Sumerians had a less elaborate concept of the afterlife.
4. Architecture: The Egyptian civilization is famous for its grand pyramids and elaborate temples, while the Sumerians built large ziggurats, which were stepped structures with temples on top.
5. Trade: The Sumerians had an extensive trade network and traded with various civilizations, including the Egyptians. However, due to its geographical location, Egypt had less contact with other civilizations and relied more on internal resources for its economy.
