“UFOs” are just not publicly identified. To the US, these are foreign aircraft and not aliens
Sadly the “new” information is wholly uninteresting to anyone but the aforementioned conspiracy theorists
I love sci-fi movies and theoreticals about “alien” life, but the moment someone tells me mystery Russian spacecraft or a flock of geese that “science can’t explain” I get a headache and feel bad for humanity in 2020.
To the topic, I think they’d listen to dub techno, something like The Bug
I imagine gleaming chrome and neon just blasting this on Earthlings while space rays bisect humans or zap them until their skeletons glow.
That or peacenik aliens playing some Krautrock, Ulrich Schnauss maybe?
Alternately, why not some Afrofuturism?
