Psalm 19:1 The Heavens declare the glory of God, and the sky above proclaims His handiwork. 2 Day to day pours out speech, and night to night reveals knowledge. 3 There is no speech, nor are there words, whose voice is not heard. 4 Their measuring line goes out through all the earth, and their words to the end of the world.  In them He has set a tent for the sun, 5 which comes out like a bridegroom leaving His chamber, and, like a strong man, runs its course with joy. 6 Its rising is from the end of the heavens, and its circuit to the end of them, and there is nothing hidden from its heat.

Romans 1:19 What can be known about God is plain to them, because God has shown it to them. 20 For His invisible attributes, namely, His eternal power and Divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made.  So they are without excuse.
