When the Bible says that a fool says there is no God, what does this mean? Well, one meaning is that all of us have metaphysical ideas. You know, that there could be something beyond our perception and control. When someone, despite this experience, refuses to consider or discuss the metaphysical, they are a fool. They are ignoring, despite knowledge and experience, to learn and interact with others in such a way. Refusing to acknowledge an innate aspect of human nature is to be intentionally blind. Now, you don't need to believe in the same god, but let's not play the fool and pretend that there's nothing beyond our perception and control.
