Sigh, if we do not look at history then we are doomed to make the same mistakes over and over again. You can learn a lot from reading about history, everyone needs to know history. If we do we have a better chance of being wiser, not falling prey to the same mistakes, learning about how different nations have formed, economy history, and battle tatics. History is vital to all man kind, remember that.
This question is so wildly stupid, it makes my head hurt. Of course history still matters! Even if you do believe that half the stuff in history books is false, history still matters. If you are about to be hit by a car, it doesn't matter whether there is someone telling you that there is no car coming, it still matters that there is a car coming.
