What did democritus teach

Explanation:

One of these philosophers was Democritus (c. 460–370 BCE), often referred to as the “laughing philosopher” because of his emphasis on cheerfulness. He taught that there were substances called atoms and that these atoms made up all material things. The atoms were unchangeable, indestructible, and always existed.

Democritus taught the theory of atomism, which held the belief that indivisible and indestructible atoms are the basic components of all matter in the universe. Thus the word atom is derived from the Greek atomos meaning indivisible.
