It is impossible to know God. What is more, all the major religions preach that it is impossible to know or understand God, or even to clearly state what God is.
All religious “scripture” insists that God is extraordinarily remote: unknowable, unseen, unheard, beyond all human comprehension. How can we know what God wants? On what basis does God choose us for heaven or eternal damnation in a flaming hell? Do we even know what we are talking about when we argue for the existence or non-existence of God?
