Romans 1:19-21

MNT(i) 19 This is so because that which may be known of God is manifest among them; for God has made it manifest to them. 20 For ever since the creation of the world his invisible nature, even his everlasting power and divinity, has been clearly seen, being perceived through the things that are made. So they have no excuse. 21 For although they knew God, yet they did not glorify him as God, nor give him thanks; but became vain in their reasoning, and their senseless minds were darkened.
