Genesis 1:23-25 (NLT)

23 And evening passed and morning came, marking the fifth day. 24 Then God said, “Let the earth produce every sort of animal, each producing offspring of the same kind—livestock, small animals that scurry along the ground, and wild animals.” And that is what happened. 25 God made all sorts of wild animals, livestock, and small animals, each able to produce offspring of the same kind. And God saw that it was good.

Romans 1:19-20 (NLT)

19 They know the truth about God because he has made it obvious to them. 20 For ever since the world was created, people have seen the earth and sky. Through everything God made, they can clearly see his invisible qualities—his eternal power and divine nature. So they have no excuse for not knowing God.
