First the term Natural Philosophy is uses to separate it into it's on thing rather than just calling it Philosophy. The Greeks had a very different idea for what we translate as Philosophy than we do. Algebra is Math, but Math is not just Algebra. Further, the term Natural Philosophy had a different scope than Science much closer to what we would call "natural science" than how it's used in modern context. So while closely related calling Natural Philosophy Science is no more accurate than calling Chemistry Mathematics they simply refer to different things.
Anyway, it's really not my definition for Science, if you want to quote wikipedia: "Science (from Latin scientia, meaning "knowledge")[1] is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.[2][a]" (https://en.wikipedia.org/wiki/Science) Notice the last of specific implementation details, that's what I am referring to.
"The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE" well before natural philosophy. The Greeks are given a lot of credit, but they the ideas are much older than them.
