What a sad picture this is in our text today. 

Romans 1:20–23 (CSB) —20For his invisible attributes, that is, his eternal power and divine nature, have been clearly seen since the creation of the world, being understood through what he has made. As a result, people are without excuse. 21For though they knew God, they did not glorify him as God or show gratitude. Instead, their thinking became worthless, and their senseless hearts were darkened. 22Claiming to be wise, they became fools 23and exchanged the glory of the immortal God for images resembling mortal man, birds, four-footed animals, and reptiles.
