atoms

Think of the smallest object you have seen. A sand particle, a mustard seed, some dust particle, or anything else that is very small. What happens if you use a microscope and a very tiny knife and cut it into two halves? You will get a smaller sand particle, a smaller mustard seed, etc. What if you cut the smaller particle again? You will get an even smaller particle.
