There's a word for this, as I think it's fair to say any evidence of atoms still takes some inference and isn't a direct observation. The word is theory [1]. That is why we refer to the idea that matter is made of atoms as 'atomic theory',

Gould: "facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts."
