Over the time, we have changed our life style by changing physical world around us. We developed new tools. We made beautiful and strong buildings to live and do businesses. We developed fastest ways of commuting. We created devices for better communication. We discovered depths of universe and invisible world of Atomic particles. After visiting moon we are aiming at other heavenly objects. We are learning about laws of nature and using these understandings to benefit human race.
We did all this because we used combination of imagination and brain. We used our cognitive thinking facilities. We managed to transfer our experiences and knowledge to our next generations and here we are, Rulers of the Earth.
But on the other side, We are still so superstitious that we just see some phenomenons which we can not explain and we tend to accept it as supernatural. We suddenly start to ignore natural laws which are governing this universe and our lives. When we can not find way to explain any phenomena reasonable then we suspend our cognitive thinking and activate our belief system to respond to it.
Our superstitions are closely related to our religious beliefs. Religion being a supernatural belief system make it possible to give space to superstitious things and events in our life.
