The latest revelation about a civilization of more than 6000 years that history books are also 'terrible' not daring to mention

As we all know, today there are many well-known civilizations, especially the 4 most famous ancient civilizations: China, ancient India, Babylon and ancient Egypt. Among them, the Babylonian civilization is related to the civilization that we will talk about. The story takes place in the vast Mesopotamian region of West Asia. Four thousand years BC, a group of people from the East arrived in Mesopotamia. Here, they created a civilization that shocked and influenced the world until now.

However, who are they and where do they come from? The answer is still unclear, but the Akkdads later gave this group a name: the Sumerians, and the civilization they created is also called the Sumerian civilization. It seems that the Sumerians were not good at fighting nature, they were like a bright star that accidentally fell to Earth.

Their culture included a group of city-states, including Eridu, Nippur, Lagash, Kish, Ur and the first city - Uruk.

At its height around 2800 BC, the city had a population of between 40,000 and 80,000 and was considered one of the most populous cities in the world at the time. The architecture of this area is also very special as each city and state of Sumer is surrounded by a wall built of flat-convex mud bricks. However, because it is not mixed with mortar, it is easy to degrade over time.

These people came to the arid but still fertile lower reaches of Mesopotamia, where they invented irrigation techniques and successfully used water from the Euphrates and Tigris rivers to irrigate fields. They invented ditches, water structures, used drainage channels, and invented advanced water flow control technology. What is more frightening is that these works are all managed by dedicated people. In addition, the Sumerians tamed a large number of wild animals to help them plow the land and transport goods, they invented the plow, learned how to plow the land, and used cattle for weeding.

The Sumerians were very good at creating words.

4000 BC, a group of people from the East arrived in Mesopotamia. Here, they created a civilization that shocked and influenced the world until now.

The Sumerians were very good at creating words. They created the world's first hieroglyphs, which later gradually evolved into hieroglyphic writing. In an age when other parts of the world still used knotted ropes to convey information, or babble, or orally, the Sumerians developed an enormous writing system, and they used words as records of letters, writings, etc. Later, the Persians evolved and improved on the basis of the Sumerian script and formed the later Persian script.

The Sumerians had an extremely high level of mathematics. We can imagine what level they belonged to in an era more than 6000 years ago. They learned to use fractions, add, subtract, multiply, divide, and solve equations. Invented the decimal, hexadecimal and hexadecimal system. For example, they divided the circle into 360 degrees, dividing the time into 1 hour of 60 minutes and 1 minute of 60 seconds. The Sumerians even calculated the areas of irregular shapes and the volumes of some cones.

It seems that the Sumerians were not good at fighting nature, they were like a bright star that accidentally fell to Earth.

A shocking example is that the Sumerians 6000 years ago were able to calculate the result of a 15-digit calculation, written in Arabic numerals: 195,955,200,000,000. It should be understood that it was not until after AD 1600 that the European perception of numbers was gradually accepted because of the popularity of great mathematicians such as René Descartes and Leibniz. It was not until the first century that Europeans knew the concept of 1,000,000. So Europeans at that time believed that if there were more than 1 million everything was called infinity. Therefore, the term millionaire at that time was born from that, because people did not know the concept of a millionaire, let alone the concept of tens of millions or billions. And this kind of mathematical achievement, 6,000 years ago, the Sumerians did very well.

The Sumerians were also good at astronomy. By observing the Moon, the Sumerians divided a year into 12 months, 6 months was 30 days, 6 months was 29 days, a total of 354 days in a year, and used the leap month method to compensate for time errors. In addition, the Sumerians created the term "week" and defined 7 days as a week. Not only that, the Sumerians at that time were able to distinguish between stars and planets. The Sumerians also observed the Earth's orbit around the sun. This knowledge of astronomy embarrassed Nicolaus Copernicus and Giordano Bruno later on as well.

Decline

In 1940 BC, Sumer was invaded by the Elamites and looted the city-states. Then, in the Hammurabi dynasty of Babylonia, the Babylonians unified the lands of Mesopotamia, the Sumerians perished. By about 1700 BC, the Sumerians were gradually assimilated with the Assyrians and Babylonians.
