If you ever doubted the existence of UFOs, this video will convince you of their veracity. Never before has such a clear sighting of an alien space-ship been recorded on video. (As hard scientific evidence, this is topped only by a video of an alien corpse kept in a Russian freezer, filmed last year).

The man – identified only as Space999dude – who witnessed the awe-inspiring scene wrote on Youtube that: “The ufo over london thames estuary seems too bright for a boat and looked like it was above the water.”

He explains the poor quality of the footage by saying that he was a long way from the alien craft and that even with his camera’s 40x zoom the object was hard to film.

Space999dude is not new to alien sightings and has posted other clips, including ‘Strange sound recorded over London‘ to his Youtube channel.

” I always carry a camcorder in my car as saw something a few years ago and think more people should be looking and keeping cameras at the ready,” he says.

Alien sighting over the Thames Estuary:

Shockingly, some viewers have failed to see the potential of the Thames Estuary UFO clip as final conclusive evidence for imminent alien attack.

“Why stop filming after 53secs? That’s the first sign of a hoax. Indoor lights reflected in the window is my guess,” wrote one person.

“Let me guess. After 53 seconds , the aliens took over your brain, made you turn off the camera, and pulled an anal-probe train on yo’ as$, right?!” said another.

Taking up the 53 seconds theme, another UFO-hater said: “Yeah, and like everybody else says, why did you switch off after 53 seconds and why didn’t you zoom out to give us some perspective? No good telling us it was a 40 x zoom without something to compare it with.”

What is wrong with some people?

Take shelter, we say.
