Democritus proposed his ideas on the nature of matter around the 5th century BCE, specifically around 400 BCE. He introduced the concept of the atom as an indivisible particle that makes up all matter, laying the groundwork for atomic theory. His thoughts were largely speculative and philosophical, lacking experimental support, but they significantly influenced later scientific thought.
The word "atom" comes from the ancient Greek "atomos" meaning "uncuttable". The concept of atoms being the smallest part of an element is a natural philosophy that developed in several ancient traditions, and it is therefore difficult to say "who" was the first person to make this claim.
The Greek philosophers Leucippus and Democritus
The idea that matter is made up of atoms was proposed by the ancient Greek philosopher Democritus around 400 BCE. He believed that all matter consists of tiny, indivisible particles called atoms.
•460 B.C. did a Greek philosopher, Democritus, made the idea of atoms. He asked this question: "If you break a piece of matter in half, and then break it in half again, how many breaks will you have to make before you can break it no further?" Democritus thought that it ended at some point, a smallest possible bit of matter. He called these basic matter particles, atoms. I doubt he had any opinion on that.
Democritus' response was... There is a limit, if it is to remain in its original form. He concluded that matter can only be divided to its smallest particle... an atom, to retain it's physical characteristic.
Atomos is the name Democritus gave the smallest particles.
John Dalton used experiments and scientific tools to study matter. Aristotle and Democritus did not use such methods in their studies of matter.

To Democritus the atom looked like a marble. Democritus theorized that matter could only broken down into pieces of a certain size. These pieces which could not be broken any further were called atoms.

Democritus suppositions on the properties of matter
Democritus was correct in proposing that matter is composed of indivisible particles called atoms. Aristotle, on the other hand, believed that matter is infinitely divisible and that everything is made up of a combination of the four elements. Modern atomic theory supports Democritus' view that matter is made up of discrete atoms.
Easy, Democritus's
