Is History Worth studying?

I think that History is worth studying because If we don't Know History then the world wouldn't be the same and everybody would have problems about The world we have today.I also think that history is worth studying because all of the people wouldn't know what happen in the past like How the WWII Ended Or about the Bill Of Rights also how did they invented others stuff.(planes,telephones,cars,etc.)So I think History is worth studying
