To play Devil's advocate here, since I don't believe for a second that any of this is actually aliens - even knowing that alien life exists, much less
intelligent life that's aware of us, fundamentally transforms the way we contextualize ourselves and the universe. And knowing that certain physics-defying technologies like faster than light travel, anti-gravity, etc. apparently exist would completely turn our existing scientific models on their heads.
You're right though, most people still have to go to work, and have other more pressing issues to deal with. I'm reminded that many Americans are convinced that we've already been through two alien invasions (the "New Jersey drone" sightings last year and the "Chinese spy balloon" incident in 2023, both of which were strongly wrapped up into the UFO conspiracy narrative) and that the US government has confirmed, officially and on record, that aliens are real and UFOs are alien spacecraft (they've done nothing of the sort.) Yet there isn't panic in the streets. People compartmentalize and move on with their lives if it doesn't affect them personally.
People still had to go to work when Einstein discovered relativity, but that still mattered in the long run. If any of this were true, in the sense of being actually aliens, it would still matter.
Even if the truth is just that are apparently physics defying craft that the government is aware of but doesn't know where they come from, and all of the rest of the UFO and conspiracy stuff is nonsense, it's just weird shit in the sky that's definitely actually there, that's still interesting.
