If scientific progress had not progressed now, we could not live as it is now. Scientific progress has greatly affected people's lives. If not for scientific progress, people would not be able to live as long as they are now. Thanks to scientific progress, we are less likely to get sick, and live longer than our long-standing ancestors. People have no doubt become smarter and more educated! Now, thanks to scientific progress, we are exploring other planets, oceans, seas and much more! Without a doubt, I can say that this progress is very important for us! Now people are progressing further, creating a cure for new diseases and the like. People have already overcome and discovered many different diseases, and saved thousands of lives. This progress is without a doubt very important to us.
