Belief has nothing to do with facts. Whether we believe in a concept, an idea, or in a phenomena that naturally occurs does not change the existence or non-existence of such. But most of the time, a lot of our actions are driven by belief, no matter how irrational or strange they may be. That is the psychology of belief.
You may have encountered people who hold onto certain convictions despite the lack of evidence to support them. No matter how contrary to reality, whether they are able to tangibly witness or perceive the idea, they will continue believing in it. And that's because our brains can distort our perception of reality to support our own convictions, despite the presence or absence of a physical evidence or an occurrence that proves the contrary.
