Science is, and has been, revised conclusions from observable facts, experiments and hypotheses.

Science is the best tool mankind has and will ever have.

[Hendrix]

"Science is, and has been, revised conclusions from observable facts, experiments and hypotheses."

That is just another way of saying scientific theory is an educated guess based on imperfect facts, and its conclusions may change as more information is known because the conclusions are merely educated guesses.
