What is Science & where it's used in our life?

From the beginning of human civilization Science used by everywhere 

From that time Human beings are used many methods and techniques to survive on this earth. By using the method of science they have done great work. The first of which comes with rubbing with rocks and setting it on fire.

And with this fire, they used to do various tasks such as self-defense, cooking, and many others. The beginning was to rub rocks with rocks and then to gradually merge with science as civilization progressed. When people learned the use of science, they found that there was a use of science in every step of life. In this period of the 21st century, we wake up in the morning and begin to sleep in the night until we see the use of it in every case. Science and technology have made our lives a lot easier. we can do many things very easily, such as talking to loved ones from one end of the world or exchanging information.

From the standpoint of Science:

Let's think about of water. 2 atoms of Hydrogen and 1 atoms oxygen mixed in ratio when water is made. There is a lot of hydrogen and oxygen in the world but without a certain ratio, they are not capable of producing water. And that is science. Finally, there is no place where science and technology are not used.
