Gravity is borderline magic to this day.
To be sure, an alien UFO would be borderline magic to us, not the alien, unless that alien doubled as a prick (“Can anyone else explain a successor theory to general relativity? No? I’m the wizard here.”), and magicians are pricks (“I know something you don’t know, I can do something you can’t do, lalala”). All they have to say is “yep, it’s magic, to you” and normies will just nod.
Some higher dimensional alien could probably cosplay as God and convince even hardcore atheists. That’s all God is. A sufficiently godlike alien.
