Many people think that if they cannot tangibly prove God exists (with their limited capabilities), that He must not exist.
The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned.
1 Corinthians 2:14
Can you fathom the deep things of God or discover the limits of the Almighty?
Job 11:7
