Completely agreed. The null hypothesis on that has always fallen on extraterrestrials, assuming we know everything about every single cubic meter on earth, which is anthropomorphically flawed. I never really speculate on what it was, exactly, because i don't have enough data. My first assumption is man-made, not extra-terrestrial or otherwise. It could have been ball lightning or some deception system for false radar return as someone mentioned earlier, but this thing had size to it. it wasn't a reflection. I've seen (vary rare video) examples of ball lightning also, but they don't move like what i saw.
