Does history matter? Explain

Does history matter? Well of course it does, it provides great intel in what we shouldn't do and what we should do, but at the same time history can't be trusted. If it's writen by the winners we only get their part of the story and not of the losers. History does a great deal for us down to war stratagies and geographic location of things. In my opinion I think history matters alot more then what other people think.
