Genesis 11:2-4

As the people migrated to the east, they found a plain in the land of Babylonia and settled there. They began saying to each other, “Let’s make bricks and harden them with fire.” (In this region bricks were used instead of stone, and tar was used for mortar.) Then they said, “Come, let’s build a great city for ourselves with a tower that reaches into the sky. This will make us famous and keep us from being scattered all over the world.”
