I guess that depends on how you define a scientist. I'm sure even pre-historic tribes had members that were smarter than others and like to study things and make inventions.
I feel the same way. Is leavened bread science? Nixtamalization? Collecting raw materials with interesting properties? Observing river and ocean currents? Making plant based medicine, dyes, or clothes? Tanning hides?
There are so many skills developed and improved on over time for us to have gotten to where we are. Ugg the cavemen or an early farmer or a stargazing shepard wouldn't have called themselves scientists, but they were most certainly doing science.
