Noah was a man Of faith, Hebrews 11:7 "By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; by the which he condemned the world, and became heir of the righteousness which is by faith."
That is why Noah was Mention as a righteous man, blameless in his generation, someone who walked with God, just as Enoch.
