That's illogical.
Suggesting one possibility does not necessarily mean the elimination of all others.
To a person of faith, aliens/ extraterrestrials/extradimensionals might be demons presenting themselves as aliens.
Or they might not be demons at all and instead be beings from another world or dimension.
Both possibilities can exist without being mutually exclusive.
What I’m saying is that when presented
with a difficult situation, to jump to
“God will handle it,” is a copout.
