Agnosticism

Agnostics believe that God has given insufficient evidence for His existence. But God disagree. "For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse (Romans 1:20, NASB)."

In the olden days, men thought that the world was just a small place and the sky was a high ceiling. They thought that if they build a tower tall enough, they could reach God's heaven (Genesis 11:1-4). It would be understandable if their opinion of God was low. But Noah and his sons were still alive. They could ask them.

Today, we know how big and complex our universe is. It is still beyond our comprehension. We even learn engineering (biomimetics) from "mother nature". However, we attribute the existence of this great universe to chance based on the laws of physics. We assigned the eternal attributes of the Creator to His creation.

"The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. There is no speech nor language, where their voice is not heard. (Psalm 19:1-3 KJV)"
