And by aliens I mean, outer space creatures and UFO. For whatever reason all UFO sighting footage looks either fake or like recorded with a Casio keyboard. And I find hard to believe we don’t have any decent footage of them with all the surveillance and technology we have now.

I’d go one step further. Not only does our current understanding of the universe not include any possibility for FTL, as far as we understand FTL would completely break reality. Science actively excludes FTL as a thing that can exist.
Wormholes might be an idea, but they aren’t even at the theory level yet. More of a conjecture that fell out of some math, but can’t exist in the real world.
To be fair, you could have said the same thing about black holes at some point. But even if wormholes exist, they may not be “constructable” or anything of that sort. It may just as easily be a hole from nowhere to nowhere and you can’t change it or move it, it’s just there.
