So, if magic exists, there also might be aliens. Got it.

Well, we haven't observed anything that gives even a hint that something like that exists.
The matter / antimatter disparity is still quite a mystery. But we don't see any evidence of antimatter out there in any significant quantities. So if aliens want to use it, they have to make it the hard way, just like we do.
Beyond current state-of-the-art technology would make manufacturing and containment of antimatter easier, but even then it is a long way from practical.
