Why does the bible say no one seeks the Lord and everyone says they seek him?

Rom 3:11. Why does the bible say no one seeks Gods righteousness and are all sinning and people say they are seeking him but no one can be righteous as God? Can it be no one seeks his face and are sinning day to day because they do not seek him for his ways to be added unto them. Sense they do not seek this understanding God can give, no one can understand to depart from evil, and are unworthy to find the glory of God, and that is heaven and the understanding of holiness.....which is the mystery of the cross and Gods love, even though you do not seek heaven, God with love came and gave heaven to you with his son Jesus nailed up to a cross, as no sinner can enter into heaven.
