Plato's Socrates said philosophy is the only true science. This was made in comparison to architecture, engineering, and art.
That is obviously a bad English translation of the archaic Greek. Neither the Greeks nor anyone else had a word for science prior to the modern era.
I cannot read archaic Greek to know what Plato intended in the original language, but the pre-Socratic philosophers were doing a kind of natural philosophy, akin to what we would call science today. Aristotle was doing natural philosophy too.
