The early Nubian civilization was based on agriculture, particularly along the banks of the Nile River. They cultivated crops such as wheat, barley, and legumes, and also engaged in herding and fishing. Trade was another important aspect of their economy, as Nubia was strategically located along trade routes that connected Egypt with Central Africa.
India's first civilization was in the Indus Valley which is located in modern day Pakistan and northwestern India. The Indus Valley Civilization (also known as the Harappan civilization) was a Bronze Age civilization that began around 3300 BCE and was one of three early civilizations in the Old World, along with Ancient Egypt and Mesopotamia.
