Romans 1:20-21

20For his invisible attributes, namely, his eternal power and divine nature, fhave been clearly perceived, ever since the creation of the world,
Or  clearly perceived from the creation of the world
in the things that have been made. So they are without excuse.
21For although they knew God, they did not honor him as God or give thanks to him, but they hbecame futile in their thinking, and their foolish hearts were darkened.

Romans 3:11

11no one understands;
no one seeks for God.
