The correct answer to this open question is the following.
I think the inventions of the early Sumerians (Cuneiform, the wheel, ships that can make sea crossings) impacted Mesopotamian Culture in that these factors made Sumeria a powerful region that influenced other ancient civilizations such as the Babylons. Let's have in mind that Sumeria-Mesopotamia was the oldest civilization known to man. They settled in the middle of the Tigris and Euphrates Rivers in the Middle East region(modern-day Iraq). They developed agriculture techniques that allowed them to grow crops in the fertile land of the banks of these rivers. They prospered and founded great city-states such as Ur, Lagash, Ur, Nippur, Eridu, and Kish.
