Why was democritus not considered on on scientist?

Democritus as an influential Ancient Greek pre-Socratic philosopher primarily remembered today for his formulation of an atomic theory of the universe. To be a scientist, one must have a degree that is related to science. Hope this answers the question.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
