How was Sumeria different from stone age?

Sumeria, one of the world's earliest civilizations, marked a significant advancement from the Stone Age through the development of urban centers, complex societies, and written language. Unlike the primarily nomadic or small-scale agricultural lifestyles of the Stone Age, Sumerians built cities like Ur and Uruk, engaged in extensive trade, and established formal governance. They also created cuneiform writing, which facilitated record-keeping and communication, distinguishing their culture from the oral traditions of the Stone Age. Additionally, advancements in technology, such as irrigation and metalworking, set Sumeria apart from the more rudimentary tools and practices of earlier periods.
