Now, I agree with your basic premise that UFO sightings are probably mostly BS since the number of sightings has plummeted since people started carrying cellphones, but notice how people aren't reporting that they took a picture and now it too small for them to see. They just stopped altogether.
Personally I still favor life being more rare than we credit it with, and that we are fundamentally alone. But regardless, the idea that we're being visited in sometimes-observed spacecraft by apparently only quasi-competent aliens is absurd in light of what we know now. If "they" are among us, they are not quasi-competent, they are competent to a level that we can barely imagine.
The UFO meme's not so different. Super-advanced races using their incomprehensibly superior technology to fling themselves across the near-infinite vastness of space are visiting us in order to. . . prank aircraft pilots, share tedious banalities and diddle butts. The word 'risible' again comes to mind.
One thing that is certain is that if no alien air crafts have ever visited earth, then all UFO videos/pictures must necessarily be unclear, because otherwise we'd see that it's not a flying saucer.
Also, they are often far away so zoom level is set on max.
I gained some respect that day for anyone who claims to have seen something, and yet has no decent evidence.
Why would it be convenient to ignore it if it was real? Legitimate evidence of extraterrestrial life would be, by and large, the most significant event in human history, and incredibly inconvenient to ignore for a virtually unlimited number of reasons.
If you wanted to get a good UFO photo or video what you'd really want is a high-resolution infrared camera. Unless our UFOnauts (whatever/whoever they are) are exempt from physics, anything using energy for any kind of powered flight must emit infrared whether it wants to or not.
Maybe in a few years.
What kind of video would it take for us to believe ?
But there are a lot of sightings captured on cell phones these days.
Many are obvious fakery. Some seem more interesting.
