a lot of people are atheists for not realizing that many things that cannot be proven by the mind and logic, a simple example is when we sleep, we never know what happens during sleep.
The fact that
we don't know this or that does
NOT means nothing about God, it simply means
we don't know (yet).
Simple as that!
Or you have the need to "know everything" and for anything you don't know "it was God"? That's living a ridiculous lie!
