Ok, we don't need science. Unless we want to live in a world with basic tools, running water, transport, life expectancy past 40, and an infant mortality rate below 1 in 3.
Remember, germ theory is science. The clothes that you wear? Science. You crossed the street this morning.... did you close your eyes and step out hoping that god would bot let you get hit or did you first consider the evidence and look both ways?
Science isn't a "thing," it's a way of thinking. Furthermore, it's the most reliable way of thinking for finding out what is true. Have scientific developments been detrimental on occasion? Sure. Not as much as religious ideologies though.
