What is the best description of scientific theory

Scientific theories are the facts of any hypothesis.

Explanation:

A scientific theory is the facts behind a hypothesis. It takes a longer time to give the observation into a theory. The scientific theory is not a guess. It is the logic behind any natural phenomena. Hence no one can challenge the theory in the future. This is the fact that can't change with a pass of time but modifications can be done if needed. The germ theory of diseases, the theory of evolution, Newton's theory on motion are examples of scientific theory. The hard work of scientists produces a scientific theory.
