The Greeks are the only culture for which we have written record verifying a concept of the atom akin to what we know today.
Democritus
He was the first person to discover the existence of atoms in the 4th century B.C.
The concept of atoms, or particles that make up all of matter, is an ancient one. However, John Dalton came up with the first scientific atomic theory in the early 1800s.
The original metric system was first proposed in 1668, and was not adopted until the mid-1670s. The closest thing the ancients had, in terms of universal use and ease of that use, were more along the lines of imperial units.
Greeks were the first to invent and set the basis for the following: Geometry (see Euclides), Astronomy (see Aristarchus), Mathematics (see Thalis), Logic (see Aristotle), History (see Herodotus), Physics (see Democritus), Medicine (see Hippokrates) etc...

I think Democritus first posited the existence of atoms.
That would be Alfred Wegener
The first person to suggest the existence of atoms was Democritus.
Rutherford
It was not John Dalton who first suggested the idea of atoms. It was the Greek philosopher and mathematician Democritus who first suggested the existence of atoms.
The currently accepted model of the Big Bang predicts that the early universe was composed of a quark-gluon plasma. After it cooled, baryons could form (baryons are particles like protons and neutrons which are made of quarks), and some time after that atoms could form. If you mean which was DISCOVERED first, atoms, by at least a couple of centuries.
John Dalton first proposed this. Today, it's called Dalton's atomic theory.
Democratus. (with an a) Dalton came up with the first model.
No. Ancient Greek philosophers postulated the existence of atoms.In 1803, John Dalton proposed an atom to explain chemical reactions that had been observed by scientists since the 1800's.
Democritus, an ancient Greek philosopher, was the first person to introduce the idea of an atom. He proposed that all matter is made up of tiny indivisible particles called atoms. Democritus' atomic theory laid the foundation for the modern understanding of atoms.
The idea of the atom was first proposed by the ancient Greek philosopher Democritus in the 5th century BCE. He suggested that all matter is made up of indivisible particles called atoms, which differ in size, shape, and arrangement.
