According to the Bible, before now, the whole world speak one common language and as a result the unity was very strong. The people existing at that time decided to build a tower in order to see God.

The tower had gone high up the clouds and God said that if he allows this people, they will be able to do anything set there mind to do… so, he decided to set confusion in there means by giving everyone different languages. Since they couldn’t understand each other, they scattered all over the world..

The point i am trying to make here is that “communication is power” just adding more point to it.
