What was one of the first things the Sumerians learned?

One of the first things the Sumerians learned was the ability to cultivate crops and domesticate animals, which marked a significant shift from nomadic lifestyles to settled agricultural communities. This agricultural innovation allowed them to produce surplus food, leading to population growth and the development of complex societies. Additionally, the Sumerians developed early forms of writing, such as cuneiform, to keep records of agricultural transactions and societal activities.
