Science is the earliest root and it comes from europe. The history of science is mainly studied about the development (discoveries) of science and scientific knowledge like knowledge that is based on scientific methods which are supported by adequate validation, including both the natural and social sciences (the history of the arts and humanities is termed history of scholarship, dentists,physicans, etc). Science is a body of the empirical, theoretical, humanatical (legal), Tand practical knowledge about the natural world, produced by scientists who emphasize the observation, explanation, and prediction of real-world phenomena.
Science in a broad sense (oldest unit) existed before the modern era and in many historical civilizations. Modern science is distinct(different and many changes) in its approach and successful in its results, so it now defines what science is in the strictest sense of the term. Science in its original sense was a word for a type of knowledge, rather than specialized word for the pursuit of such knowledge.
