Either a Government Façade(conspiracy) or Extraterrestrials. Now the "reasonable" people are in a conundrum.
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.
