I heard from a wise man once that "Magic is only science that we have yet to understand" people once believed fire to be magic but now we understand how it works; there is no such thing as magic only science we have yet to understand. However an act of god is an entirely different topic don't even get me started on that.
J.K. Rowling once said, and I quote, "Wizards represent all that the true Muggle fears: They are plainly outcasts and comfortable with being so. Nothing is more unnerving to the truly conventional than the unashamed misfit". Wizards/witches possess magical power, and they embrace that, so should the non-magical community. I revere their powers.
