Seriously, read the Aquinas proofs for God’s existence.

Read the endless philosophical and logical endeavors of those who came before us to prove that the non-existence of God makes absolutely zero logical sense, and that to subscribe to the idea that we exist simply because it is our nature to exist is indeed ridiculous. Atheists and agnostics prove the existence of God without even realizing it, because they put subjective analysis of reality on a pedestal and call it “Truth” with a capital “T.” In order to study the metaphysical, you must appeal to outside of the physical by definition.
If man made God, then what made man? What made the thing that made man? What made the thing that made the thing that made man? Unless you appeal to a source that is necessarily outside of creation (Creator), then logically, atheism is a limp intellectual exercise.
Faith ought not to be so fragile. God can only be known through faith, but it must be supplemented with reason and intellectual rigor, or else it is as thin as paper and capable of being torn to shreds when a simple notion enters your head.
