What arguments did the ancient Greek atomist philosophers use to substantiate their claims about the indestructibility of atoms and the variety of their forms?

The atomists substantiated the idea of the indestructibility of atoms in the following way – if atoms were destroyed by the impact of bodies on each other, then after a while they would all turn into monotonous minute dust, and the variety of substances and bodies in the world would become impossible. Atomists recognized that in the world, apart from atoms, there is empty space in which atoms can be located and move. They believed that all the changes taking place in the world are due to the properties of atoms.
