if aliens wanted us to know they exist, we'd probably already know
hot take: i believe in aliens but i dont think most UFO sightings are aliens at all
if an advanced civilization can cross interstellar distances, hide from radar, enter restricted airspace, and apparently avoid leaving any solid evidence behind, why would they keep doing blurry flybys and random lights for 70+ years
and if the answer is "they dont want us to know they're here", then what exactly explains all the sightings?
imo the more interesting question isnt "are UFOs real?"
it's why, after decades of sightings, we still dont have one piece of publicly verified physical evidence that everyone can examine
what's your best explanation? 👀
