Nobody needs to come up with a valid answer as to what else it could be.

Nobody can prove that it’s not a non-human object so it’s irrelevant what it actually is.

If you sat down and started reviewing every video that’s ever been filmed since video recording has been invented… You would find literally millions and millions of questionable objects that anybody could “suggest” as being UFOs.

It’s basically the same as the people that watch rocket launch videos or videos from spacewalks looking for any speck of anything moving in the background or foreground.

Analyzing video and trying to use it as proof that non-human or alien objects exist is a complete waste of energy and time.

Nobody will ever prove it with an amateur video clip or photo.
