Consider this: In the early days of the universe it expanded faster than light speed by many orders of magnitude.
That's because spacetime (and the expansion thereof) is independent to C. By working with spacetime instead of "throwing shit out the back (rocket engines), e.g. compressing spacetime in one direction and expanding it in another, you can transit distance without the problem of time dilation as well, and exceed C to an award observer without actually moving much at all.
And there's evidence of it on earth. Impressive sensory data collected by US, and confirmed by the US Gov to exhibit methods of propulsion that are impossible under standard physics.
June 2021 ODNP report of the US Gov.
Note that the encounters were repeatedly witnessed by dozens of airmen and sailors across multiple carrier groups over the last 18 years, and visual, video, and sensor data all correlated. There are two main ways this kind of flight is possible: 1) Spacetime manipulation or 2) Magic is real, and Gandalf is trying to get a ring to Hawaii.
No suggested conclusion as to what they are, but I think it's silly to say we don't know they are something, that utilizes physics outside of our kinetics.
