The Babylonians and Sumerians did not live together and were not the same people.
The Sumerians were the first to establish a civilization in these two valleys. The center of their rule was in the lower reaches of the two rivers. They used cuneiform hieroglyphics and their language was not symbolic. After the third Ur dynasty, the area was ruled by people who spoke a certain language. Today, Arabs and Jews belong to this language family.
The city of Babylon is located in the narrowest area between the two rivers at the bottom of the Euphrates (near Baghdad, Iraq), the River Gris. It can be said that it was a strategic location. It was from here that the ancient city-state of Babylon emerged, unifying the middle and lower reaches of the two basins, known as Babylonia.
The Amorites founded the kingdom of Babylon in Cuba (the famous Hammurabi and his code were Babylonian), and the Chaldeans founded the kingdom of Neo-Babylon (the biblical prison of Babylon was this kingdom).
In addition, the Akkadians, Assyrians, Midianites, Haimites, and Ezraites were involved here. These were basically Sami or Aryan and had nothing to do with the Sumerians. Most of them inherited the Sumerian cuneiform script, and the phonetic script.
Expanded Information
Around 2000BC, the Amorites founded the Kingdom of Babylon with the city of Babylon as its capital.1792BC, Hammurabi came to the throne, conquered the Sumerians and Akkadians, and united the Mesopotamian plain.
The Babylonians learned to build dykes and dams and to open canals and create rivers as they struggled with the floods. When the floods were subdued, they, like the Egyptians, enjoyed the benefits of regular river flooding.
Language
The Sumerian language was used for some time and then died out. The main language used in the latter period was Semitic. The present Arabic and Jewish languages belong to the Semitic group.
Money
The ancient Babylonians, also known as the Amorites, were far ahead of the Persians, and the earliest minted coins in the world were invented by the Lydians, who had not yet ascended to the political arena at that time, so there was no metallic currency in Amorite Babylon, and they mainly used bartering as a means of trade, with some pieces of gold, silver, copper, and other metals being used in general for large quantities of goods.
Living area
Ancient Babylon (about 30th century before - 729 years before) is located in the Mesopotamian plains, roughly in today's Iraq *** and the country's territory, in about 3000 BC, the people here established the state, to the 18th century BC. Ancient Babylonian kingdoms emerged here.
"Mesopotamia", which the Bible calls the "Garden of Eden", is an ancient Greek word meaning "the place in the middle of two rivers". It is also known as the Two Rivers Valley. The two rivers are the Euphrates and the Tigris. On this plain the world's first city developed, the first code of law was celebrated, and the earliest epics, myths, pharmacopoeias, and farmers' calendars were circulated, making it the cradle of Western civilization.
