As far as we remember, science is something that we have always been learning, starting from preschool. Science stimulates the curiosity in anyone, and is the best method we have so far for distinguishing between what is true and what is false using experiments, observation, mathematics and logic. A lot of things that we take for granted are the result of hard working scientists and engineers, some of whom sacrificed their personal life just so the next generation doesn't have to worry about the problems that kept them up at night.
Science has obviously increased our chance of survival and the quality of life. Paleontologists have found the evidence of stone tools that made manual labor easier dating as far as 2.6 million years ago. Although it can be debated whether to consider this an invention of science or not, let's look at some modern advancements, dating back to not more than 400 years, when Sir Issac Newton was born. Before he turned 26, he turned the world around with his revolutionary book "Mathematical Principles for Natural Philosophy". It was revolutionary in a literal sense, as it resulted in the industrial revolution, which was the beginning of our modern lifestyle, and is considered the most important work in the history of science. Science has also given us inventions like penicillin and vaccines, without which one can argue that even most of us wouldn't be here today. It has not only given us life, but has also made it easier. Using vehicles like trains and airplanes, we can go to places that once took our ancestors months to reach. We can talk to people living literally on the other side of the world, some even orbiting it in the International Space Station 330 km above us at the speed of around 8 km/s right now. The computers we use without thinking twice can think better than us, performing complex calculations that takes us weeks within seconds without making mistakes. We can generate enough electricity to power a whole city using only a single power source. We are also getting closer in answering the age old philosophical question, "Why are we here?" Using the tools of modern physics and astronomy, we have managed to send an interplanetary space probe farther than the ex-planet Pluto, and is currently heading out of our solar system and still sending data about other Kuiper belt objects. Not even Newton himself could have imagined that we'd be able to accomplish something this extraordinary this soon. People have already dreamed of building an interplanetary civilization, and the more we think about it, the more plausible it seems. We can build a technology to gravitationally manipulate an asteroid heading towards the Earth, so that we won't have to suffer the same fate that dinosaurs did around 65 million years ago.
Every Yin has its Yang. With every good things happening right now in the world because of science, let's not forget the Holocaust, where Nazis committed genocide by using chemical weapons to systematically murder six million Jews, around two-thirds of European Jewish population at that time. Also, Little Boy and Fat Man, the nuclear bomb fueled by radioactive elements Uranium and Plutonium dropped into Hiroshima and Nagasaki that resulted in the death of more than 300,000 people. If these sound like old news to you, what about the concerns about climate change that the businessmen and politicians of powerful countries like US so slyly dismiss as a hoax? Even antibiotics designed to kill harmful bacteria have been misused or improperly used, creating bacteria like MRSA that are resistant to antibacterials. How will we fight germs if they start resisting medicine? If our species won't die off of medicine resistant germs or a killer asteroid smashing into our planet, we'll probably perish because two or more powerful countries couldn't resist firing the nukes they've been pointing at each other since Einstein came up with E=mc2. The nuclear weapons detonating in a totally different continent will surely be enough to start a nuclear winter causing an ice age that would last for around a decade. This makes global warming sound like a walk in the park during summer vacation.
With all that being said, the benefits of science clearly outweighs the risks. Science is a method, and one can't blame the method if someone chooses to misuse it. We have something that can build interstellar civilization, or completely wipe the civilization off the face of the Earth; the only civilization we know of, and probably the only one currently out there. How we choose to use it is up to us. Science doesn't come with a brain that can distinguish between what is right and what is wrong, we do. So let's put it to good use.
