In this case, the skeptics should be silenced; these videos appear to be from different parts to the city, shot by different people (apparently of different nationalities), of exactly the same event.
Alas, the footage might be a little too good to be true.
After consulting Discovery News in-house skeptic Benjamin Radford, it quickly became apparent that there were a few oddities in the footage and technical hitches that may reveal the videos' true nature: an elaborate hoax.
"If it is an extraterrestrial spacecraft, it is a very small one," Ben told me via email when commenting on the possible origin of the "UFO."
"Judging by the size and distance of the dome it apparently hovers over, it would likely be not much bigger than a limousine. This doesn't mean it's not a spaceship, but it does make you wonder."
OK, so if this is a real UFO and it's being driven by ET, they might just be very small aliens. Why would they need a big spacecraft?
But there's doubt as to whether this light is a UFO at all, let alone an alien visitation.
