Everything is chemistry. Everything that you can observe macroscopically is made of chemicals. You are made of chemicals, your food is chemicals, you breathe chemicals, we live out of and thanks to chemicals, everything you see under the sun is a mixture of chemicals.
Everything you see or do is based on chemical concepts and processes. Fireworks going off takes place thanks to our understanding and application of chemistry. A medicine that you take to cure your illness does it so through chemical processes. A building doesn’t fall off because we know chemistry. Obviously, all these examples result from a bunch of different branches of science coming together. Chemistry, as the central science, is in charge of gluing them together.
