This is exactly what UFO nuts love. An obscure image open to any interpretation.
It could be a speck of space dust floating in front of the camera lens, but a UFO nut will proudly tell you this is proof that alien spaceships are visiting the earth.
This is also exactly why I am a UFO skeptic. Too many people Point to unidentified lights in the sky and jump to the wild conclusions of spacecraft
There are hundreds of UFOs. When you see a light moving across the sky, do you know what type of jet or plane it is? If not, then it is an unidentified flying object.
I know what you meant, though. I don't believe any intelligent aliens from outer space are visiting us, either. I used to want to believe, but the facts don't fit.
