While you researching the Sumerians in relation to your YouTube post, it's interesting to note the many things that have shaped our world that can be traced back to these people:-
From the Sumerian civilization, we inherited key innovations like writing (cuneiform), the wheel, the concept of a calendar, irrigation systems, basic geometry, the 60-minute hour, early forms of law, literature (including the Epic of Gilgamesh), and the development of cities; essentially, laying the foundation for many aspects of modern civilization as we know it today.
Key points about Sumerian contributions:
Writing system:
The most significant contribution is considered to be the invention of cuneiform, the first known writing system, which allowed for record-keeping and communication advancements.
Mathematics:
Sumerians developed a number system linked to the number 60, which is why we still use a 60-minute hour. Also 360 degrees in a circle, even down to our imperial system of 12d to a shilling and 240d to 1; all based on the number 6.
Technology:
They invented the wheel, which revolutionized transportation.
Agriculture:
Sumerians pioneered advanced irrigation techniques to cultivate crops in the fertile Mesopotamian plains.
Urban development:
They established the first known cities with organized structures and complex societies.
