Extended data
Four ancient civilizations: ancient Babylon, ancient Egypt, ancient India and China. However, except for Chinese civilization, the other three ancient civilizations have disappeared in the long river of history.
The kingdom of ancient Babylon has long since disappeared in the desert. Now the country based on the primitive Babylonian civilization is called the Republic of Iraq, which has nothing to do with it. The once extremely prosperous hanging gardens are now only empty ruins.
India today is not ancient India. The representative of ancient India, "Halaba culture", has been extinct after foreign invasion and destruction. In summer, Greeks, Cypriots, rest people and British invaded India successively. It was not until 1947 that India became independent and established a republic. The civilization of ancient India has hardly survived to this day. I can't even read the text of archaeological discoveries.
