Is it true that Sumerian civilization documents reveal that human ancestors came from outer space?

Sumerian civilization refers to Sumerian civilization with Sumerian literature as the main symbol. Sumer, known in ancient times, is located in the lower reaches of the Euphrates and Tigris rivers in southeastern Iraq today.

Sumerian civilization is not completely equivalent to the civilization created by Sumerians. There is a Sumerian civilization recorded in writing for more than 3000 years in the two river basins, which can be roughly divided into two stages according to the language. First, the period from uruk IV around 3200 BC to the establishment of the Babylonian Empire (BC18th century) can be called "Sumerian civilization". Second, the period from the establishment of the Babylonian Empire to the demise of the Persian Empire (4th century BC) can be called "Babylonian-Assyrian civilization".

Sumerians were one of the earliest ancient peoples to enter the Mesopotamian plain. The name Sumer comes from the pronunciation of Akkadian people later. Because Sumerians came from the dark-haired race in the Far East, Sumerians called themselves "blackheads" in their descriptions on stone tablets.

During the period of 1922- 1934, British archaeologist Wu Lai led an archaeological team to excavate Ur, the core settlement of Sumerian civilization in southern Mesopotamia, on a large scale in the quarter of 12, revealing a panoramic view of the site from a small village 7,000 years ago to the most prosperous civilized city in the world, and finally abandoned around the first year of AD. ..

The wheel was invented at the beginning of the Sumerian era (about 3200 BC). Sumerians may have been inspired by pottery wheels, because Iranian wheels were used to make pottery as early as 4000 BC, and were introduced to Sumerian by Iran about 500 years later.

Sumerians followed the full moon for a month. A year is divided into 12 months, of which 6 months have 30 days each and the other 6 months have 29 days each, making a total of 354 days. This is 1 1 many days less than the time for the earth to go around the sun once a year, so they created a method to set a leap year. This is the solar calendar. As for whether Sumerian civilization came from outer space, people have different opinions. I think there is no basis and it is not very credible.
