Things can exist in the technologically fascinating middle ground between completely boring and aluminum foil hat alien invasion. If governments are investing into developing stealth balloons then I guarantee there is fascinating technology that we don't know about that I am excited to know more about. This is an ideal place to discuss it.
Journalist: "Can you prove beyond all doubt the moon isn't made of cheese? Have you confirmed it firsthand? Have you stood on the moon and tried to take a bite of it yourself?"
General: "What??? Uh, I haven't been to the moon, so I guess I'd have to answer no."
Journalist: "Moon made of cheese? Senior U.S. general says not ruling out anything yet"
'We're not sure what it might be', is very different from the usual 'No comment' that we'd been so accustomed to.
You'd wonder whether that's because of:
A: Misdirection B: Genuine uncertainty C: A new policy with which to address social media
But you know, just the need to shoot something down, disclose that fact publicly, but not reveal exactly what it is (even if it is just a terrestrial source), is pretty freaky.
If cnn says something like "Pentagon has officially confirmed aliens are here." or "Pentagon has officially confirmed China has new stealth tech." then we can take a look.
I think the truth is far more likely to involve the government keeping secrets than aliens, but in both cases, something is up.
Reasonable people are willing to accept the likelihood that these are Chinese spy balloons or other mundane (not extraterrestrial) objects, and even that the government is pulling some kind of bullshit act with it in the media for the sake of politics or optics. It isn't the case that any conspiracy afoot is equally as likely as aliens. It isn't going to be aliens.
