BIG agreed! There's numerous sightings that nobody has ever been able to explain, most notably recently the 2004 USS Nimtiz sightings, and as evidenced by this paper I linked elsewhere in the thread (https://www.mdpi.com/1099-4300/21/10/939/htm) it is incredibly unlikely for some of the objects being sighted to be experimental military aircraft or otherwise human-made, it's just far too big of a technological leap.
It should also be noted that the current status quo of 'UFOs aren't real, people are stupid and misidentify shit and that's all it is' (not to say that people don't misidentify shit, that's anywhere from 90-75% of sightings depending on which analysis you prefer) was deliberately cultivated by a USAF backed scientific 'study' that was working to 'prove' UFOs fake from the moment it started, the Condon Report. Wikipedia has a great summary of all that bullshit (https://en.wikipedia.org/wiki/Condon_Committee) and I urge you to take a look at the actual report itself, as it blatantly ignores it's own data in order to come to the preset conclusion of 'UFOs ain't real'. (https://files.ncas.org/condon/text/contents.htm)
I do want to stress however that I don't believe there's some giant cover-up going on. My personal research on the subject suggests that it's fundamentally a matter of the authorities involved falling victim to the same environment of ridicule and dismissiveness that the CIA cultivated with the Robertson Panel (https://en.wikipedia.org/wiki/Robertson_Panel) because they believed UFOs weren't real, and considered UFO sightings clogging up reporting lines for unknown aircraft to be a national security threat. In the academic world thinking that UFOs should be studied means you'll be considered a total quack by nearly everyone, and your career will be ruined, and in the military world doing anything but ignoring UFO sightings and reports has been a good way to get ridiculed and passed over for promotions. This has only started to change very recently, as it seems like the US Navy has been taking something of an interest in the subject after multiple high-profile very credible sightings, and there's been a concerted effort from some former members of the US Intelligence Community to lift the stigma surrounding the subject.
