The definition of science has never been settled. There are things which, broadly speaking, are accepted as scientific or not, but providing a rigorous grounding of and definition for the concept of "science" is a centuries-old open question, thanks largely to the problem of induction. Falsificationism is one possible solution that's been proposed, but it is not the only one, is not universally accepted, and you really should probably do some background research on the topic before arrogantly spouting off about how you have the one true answer that some "army of philosophers" with "silly meta arguments" can't manage to come up with.
