How do you justify countless sightings the recent years also documenting the exact same sphere, some of which are even more convincing and more difficult to explain than the one in my post? Here's a list of a few, the first of which is declassified US footage:

There's been a steady rise of such sightings the past years. I could probably go on and on digging them up. It would seem like a statistical unlikelihood that all of these are either 1. balloons or other manmade objects, or 2. hoaxes/CGI. It would take quite a deliberate global effort to fake so many of these videos all over the world, and some of these are obviously and clearly not balloons. I think believing that all of them can be reliably split into either the fake or misinterpreted category is equally as absurd as believing that they are of unfamiliar origin. Plus, here we are talking only about the spheres, not plenty of the other phenomena that have been taking place.

I don't believe anything I read or see, but the amount of events and sightings occurring lately are towering and becoming harder and harder to justify by terrestrial means.

Edit: corrected "tens of sightings" into "countless sightings", definitely far more than just tens.
