Imagination and fantasy help human beings to speculate upon the possible explanations for the complexity and unpredictability of the phenomena in the universe.

Science does not promise absolute truth, nor does it consider that such a thing essentially exists. Science does not even promise that everything in the Universe is controllable to the scientific process. I believe that imagination and fantasy plays a major role in helping a human being in getting possible outcome or result that can explain the complexity and unpredictability of the phenomena in the universe as things related to science are based on imagination as science born with imagination only. That is why, imagination and fantasy help human beings to speculate upon the possible explanations for the complexity and unpredictability of the phenomena in the universe because these things do not exist in reality that everyone could accept.
