Answer 1

This is back to the greek thinkers, they used to think abuot elements such as fire, water, air and earth

They used to think that matter was evnetually not divisible, that is, eventually you will stop dividing matter

This was mainly to the fact that infinity was not considered a natural property, so Democritus stated this law/theory, which stated matter is composed of indivisible thing called a-toms, i.e. literally from Greek atomos (n), from atomos (adj) that cannot be divided
