What is the oldest civilization on Earth?
That's fascinating. Were these civilizations aware of each other's existence?
It's believed that there was some trade and cultural exchange between ancient Sumer and the Indus Valley Civilization, but there is no evidence of direct contact between ancient Sumer and ancient Egypt. However, both civilizations did share some similarities, such as the development of hieroglyphics in Egypt and cuneiform in Sumer.
