Why do people believe in supernatural things like magic, astrology, ghosts if they have science?

I think that the main reason is the fact that we seek explanation for everything we don't understand. Even the slightest, stupidest thing. What is more, we like to believe that the world is not randomised based on our choices, but that there's something dictating the outcome. Back in the day people would come up with many things just to make their lives a little bit easier to comprehend the beliefs don’t tend to die out easily, so they were passed onto other generations, hence people in the modern world like to have their own understanding of some things.
