Romans 1:20-21

There are things about God that people cannot see—his eternal power and all that makes him God. But since the beginning of the world, those things have been easy for people to understand. They are made clear in what God has made. So people have no excuse for the evil they do. People knew God, but they did not honor him as God, and they did not thank him. Their ideas were all useless. There was not one good thought left in their foolish minds.
