Hello! It's a very good question, I hope and this post will answer something we would do without science.
In my opinion what I would answer to that question would be that people would not live long because we would get sick and diseases would not have any cure and apart we would not have furniture, and we would all be the same, we would have the same clothes, shoes, etc., and we could not distinguish other people, everything would be the same, we would smell the same, everything would have the same flavor, color, and texture that is why thanks to chemistry, everything is different and people are not the same. Also the food would be very few, plagues and insects, the harvest would be little, the lack of light, telephone, television, computers, radios etc. that make it possible for us to communicate, gas and gasoline would not exist and, of course, much less airplanes, cars, trucks and boats would also not exist in art or music.
Since science is everything, without science we would still be living in a primitive world without discovering the earth, the stars and the universe would be ignorant people without knowing our world. We use science at any time from when we get up until we fall asleep. We would also have many diseases why they would not discover that water can be purified. The babies some of them or the great majority would be born with disabilities, diseases or die at birth or a few days since they would not be given the necessary care, it would be a dirty and polluted world and there would be many diseases due to contamination, not they would discover the new bacteria.
