Why does the movie have such a name?

I didn't quite understand why I chose such a name, so I looked up the story about Babel.

Babel is the tower of Babel mentioned in the Bible story, which was built by the descendants of Noah. Chapter 1 1 of Genesis in the Old Testament once described that in ancient times, everyone in the world spoke a language. People moved eastward to study, went to a place called cinar, found a plain and settled down. They plan to build a tall tower, the top of which will soar into the sky to show the strength and unity of the people. The tower was built soon. This alarmed the Lord in heaven. He was jealous when he saw that the tower was built higher and higher. He thought to himself that people in the world are all one nation and speak one language. Together, they can work miracles. How does God rule mankind? So the Lord used magic to confuse people's accents, so that they could not communicate, and the tower could not continue to be built, and finally it was not built. This is the legend about the Tower of Babel.
