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.

And it sounds like you are sure the laws of physics don't apply to aliens.

Extraordinary claims require extraordinary evidence.

[davidivadavid]

The whole point is that we don't know what the laws of physics are.

You've already proven when present with extraordinary evidence your reply will remain "Extraordinary claims require extraordinary evidence."

Even Isaac Arthur did a video on the Navy's videos, and he's more open to this than you. Please give this a rest -
