* Atoms are the building blocks of everything we can see and touch. Everything from the air we breathe to the chair you're sitting on is made up of tiny particles called atoms. These atoms combine in different ways to create all the different substances we see around us.
* Atoms are made up of even smaller particles. Atoms themselves are not the smallest things in the universe. They are made up of even smaller particles called protons, neutrons, and electrons. These particles are fundamental, meaning they can't be broken down into anything smaller.
So, while it's true that everything we can see and touch is made of atoms, atoms themselves are made up of something even smaller.
There are some things that are not made of atoms:
* Light: Light is a form of energy that travels in waves. It's not made of matter, and therefore not made of atoms.
* Dark matter: Dark matter is a mysterious substance that we can't see, but we know it exists because of its gravitational influence. We don't know what dark matter is made of, but it's likely not made of atoms.
* The Higgs boson: The Higgs boson is a particle that gives other particles mass. It's a fundamental particle, like protons and neutrons, and it's not made of atoms.
So, while it's true that atoms are the building blocks of the vast majority of what we see and experience, they are not the ultimate building blocks of the universe.
