Oh science played an enormous role, trust me. Way back, in the dark ages era, we only jad fire to protect ourselves, to keep our bodies warm, we only had those raw materials that we can find in our surrounding to suffice our need for our daily survival. But now, as the minds of humans get more and more knowledge, we tend to discover more things and innovate more for the improvement of our living. For example, who ever thought that with enough electricity and other concepts of science, we could invent rice cookers? electrive stoves, etc?
