Samuel Huntington divided the current world civilization into eight major civilizations, namely Chinese civilization, Japanese civilization, Indian civilization, Islamic civilization, Western civilization, Orthodox Christian civilization, Latin American civilization, and African civilization.

1. There is no doubt that ancient Greece is the source of Western civilization. But the ancient Greek civilization did not fall from the sky, it was strongly influenced by the ancient Egyptian and Babylonian civilizations from the beginning, so the ultimate source of Western civilization can be traced back to ancient Egypt and Babylon.

2. Ancient Greece is the open source of Western history, which lasted for about 650 years (800 BC - 146 BC). Located in southern Europe, northeastern of the Mediterranean, it includes the southern part of the present-day Balkan Peninsula, the west coast of the Asia Minor Peninsula, and many small islands in the Aegean Sea. In the century B.C., especially after the Greco-Persian Wars, economic life was highly prosperous, and a splendid Greek culture was produced, which had a profound impact on later generations.

The ancient Greeks had deep attainments in philosophical thought, history, architecture, science, literature, drama, sculpture and many other aspects. After the demise of ancient Greece, this civilizational heritage was destructively perpetuated by the ancient Romans, thus becoming the spiritual source of the entire Western civilization.

The Two Rivers Civilization is also known as the Mesopotamia Culture, or the Two Rivers Civilization. It refers to the civilization that developed in the two river basins of the Fertile Crescent (the Mesopotamian plain between the Tigris and Euphrates), and is the earliest civilization in Western Asia. It is mainly composed of Sumerian, Akkad, Babylonian, Assyria and other civilizations.

Historians refer to the Sumerian civilization between 4000 BC and 3000 BC"Early high civilization"The cultures of this period include the Uruk culture and the Jemdettnesr culture.

The Sumerian city-states of this period already existed, and the Sumerian script already existed, but the history of this period is still very unclear, and the reasons may be due to a number of reasons, such as insufficient archaeological discoveries, or the lack of systematic historical documentation of the civilization itself at the beginning of the civilization. The cuneiform documents of this period that have been discovered are mainly economic or administrative documents, and it is not yet possible to outline the complete history of the time.

The ancient Egyptian civilization is also the earliest civilization left to future generations.

It should be the Atlantean civilization.
