Dude science is trial and error, experimentation and observation. It doesn't require lab coats and beakers. We are all scientists on one level or another. Who ever was doing the trial and error (spelled experimentation) on the first wheel was a scientist like it or not.
They weren't professional scientists and didn't have a degree, or lab coat. There were "scientists" at Stonehenge and building pyramids. Written language probably was less "scientific" but all advances were basically by "scientists", in whatever low tech existed at that time.
Donald Trump: “ Black guys counting my money! I hate it. The only kind of people I want counting my money are short guys wearing yarmulkes… Those are the only kind of people I want counting my money. Nobody else…Besides that, I tell you something else. I think that’s guy’s lazy. And it’s probably not his fault because laziness is a trait in blacks.”
