It depends.
There are some known conditions that create hallucinations, so if some of those conditions are present then it becomes a more plausible explanation
than extraterrestrial presence on Earth.
But if those conditions are not present and there isn't any evidence of their presence at the time of the event, then hallucinations become as good
as any other explanation.
Extraterrestrial presence on Earth (not as well documented as hallucinations) may also be an explanation, although always less likely to be the right
explanation, like all other explanations for which we don't have strong evidences.
The nature of the evidence has nothing to do with it.
If someone doesn't consider the existence of aliens to be possible than any evidence can be rationalized away.
It does, when someone
compares one witness testimony with a physical evidence, for example.
With witness testimony we don't have any physical evidence, only a description of what the witness witnessed, so we cannot go further than ask
questions, and the witness becomes another obstacle between us and the knowledge of what really happened, because now we have a testimony that we
don't know if it's true, if it's accurate, if it misses something that witness didn't noticed for some reason, etc.
Physical evidence is just that, you can pick up a piece of some strange metal, for example, and do some tests.
They will not tell us if it was really an extraterrestrial related event, but at least we know that the piece of metal is not lying, did not forgot
about some of its properties, etc.
Obviously, if someone thinks that extraterrestrial life is impossible, they will never consider it as an option, but then they will get more problems
explaining the piece of strange metal than the witness testimony.
Also, people like that are not sceptics, a sceptic
must accept any possibility, including those that he/she does not know yet.
At least that's what I do.
