“The heavens declare the glory of God; and the firmament shows His handiwork. Day unto day utters speech, and night unto night reveals knowledge. There is no speech nor language where their voice is not heard. Their line has gone out through all the earth, and their words to the end of the world. In them He has set a tabernacle for the sun, which is like a bridegroom coming out of his chamber, and rejoices like a strong man to run its race. Its rising is from one end of heaven, and its circuit to the other end; and there is nothing hidden from its heat.” Psalm 19:1-6.
Sometime after the creation of Adam and Eve on the sixth day of creation, see Genesis 1:26-31, they rebelled against God by eating the fruit of the tree of the knowledge of good and evil.
By doing so they brought sin into the world and upon all of humanity. The details of this are in Genesis 3:1-24.
“Behold, God is exalted by His power; who teaches like Him? Who has assigned Him His way, or who has said, ‘You have done wrong’? Remember to magnify His work, of which men have sung. Everyone has seen it; man looks on it from afar. Behold, God is great, and we do not know Him; nor can the number of His years be discovered. For He draws up drops of water, which distill as rain from the mist, which the clouds drop down and pour abundantly on man. Indeed, can anyone understand the spreading of clouds, the thunder from His canopy?” Job 36:22-29.
