Alternatively, "There have always been natural philosophers, at least since the first human formulated a hypothesis about nature and tested that hypothesis with observation or experiment. The term “scientist” is much younger than the philosophy of astronomy, which dates back to pre-agricultural history."

It's an ill-formed argument either way, but since "science" (c. 1834AD) is a newer term than "φυσιολόγο" (c. 350BC), I'm going to argue my rewrite is the more accurate.

I'd also argue that the study of the stars was more religious than scientific, at least prior to Thales of Miletus (who, as far as we know, was the first epistomologist).
