Even at speeds approaching light speed ( very unlikely in any case ) , interstellar distances are still way far too great !
Why thinking of interstellar travel?
The UFO or more correctly UAP (unidentified aerial phenomenon) could

I agree the "mostly likely" interpretation of the data at this point
is a bunch of "aliens" that seem a lot like humans. Maybe they have
interplanetary capability but they seem hang out in obscure parts
of the earth "a lot" of the time.

But interestingly the "space warp technology" some physicists argue
UFO's exhibit from time to time (e.g. "shape shifting") is a potential
FTL drive.

Warp drive uses the same part of General Rel that allowed the universe
to expand to ~100 bn LY diameter in 13 bn y.

Wasn't that situation explained away by postulating that the speed of
light used to be a heck of a lot faster than it currently is .... you
know, how things tend to get slower as they age??
