I tried linking the debunk videos to someone in a HN thread, and they dismissed them and did the "do your research like I did ;) ;)" thing. I asked for any research links and read the single one they offered and argued it, but they preferred to take the authority of trained Navy Pilots to some internet rando. Neither of our opinions changed.

Their position is roughly "it has been seen by competent people, and mechanisms speculated about by competent people, so it exists, so there must be holes in our understanding of physics / future tech which makes it possible to exist, just imagine what they might be". My position is "I as a layperson can't imagine how it could work, therefore it can't work even though I have no qualifications to declare that. Instead just imagine the ways qualified people are wrong about things all the time".
