There are plenty of similarities, especially I suppose for one who arrives from the distant stars. Wizards and muggles are both human. We speak the same languages, our cultures have common origins in the ancient world.
But if their science is in any way alike to our magic it is in the way that a little row-boat is alike to your time-ship. Think of it, their healers hack off limbs and drain blood, and I am told it is not out of savagery but because they simply have no better knowledge.
Dark magic is illegal. We are not alike in the ways which matter. Magic is not like science in any way that matters. You may not know this, because you are from...abroad, but telling a wizard he is muggle-like is generally not done except with ill intent.
