Belief is not "how" we come to know God... belief is our response to knowing God.

That appears to contradict what is written in Hebrews 11:6,
"...for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him."
so I take it that you came to know God without first believing, or having the hope that there was God since a person doesn't seek something or something that they don't believe exists.
