Is Magic real? like wizards, witches.?

So yeah, i been doing so much research on magic (Magik) and i was really intrested. Not much of magician kind of question but like, wizards, witches, pangan or anything that has to do with making potions or wands or brooms. In the bible, it does say that magic was use and all, but was against the law since people used it to hurt others. Im just wondering, how do people do this, is there real witches wizards out there?is merlin real? is magic really real?
