A video on YouTube shows three mysterious shapes, with many claiming it to be robust evidence that aliens do exist. The shapes could be seen breaking out of the Earth's atmosphere and shooting upwards. The video was uploaded on YouTube last weekend.

The National Aeronautics and Space Administration (NASA) has come under fire from conspiracy theorists who say that the authorities disconnected the live feed showing the presence of three UFOs on earth. They say that it is the proof that is required.

NASA has yet not cleared its stand over disconnecting live feed from the Intentional Space Station (ISS). The US space agency has kept mum about the curious lights which are claimed to be UFOs.

Britain's Sunday Express has reported that the possibility of doctoring the YouTube video can't be completely denied; also, a trick of the light could also be behind the unexplained objects.

"Critics claim the alleged UFO sightings on the live feed are simply down to NASA's poor camera and this latest sighting is likely to be a distorted view of the moon", the paper said.

Many individuals on social media said that the video has itself made it very clear that NASA is trying to cover up the existence of extraterrestrials.

Conspiracy theorists have also previously claimed that NASA inadvertently captured extraterrestrial activity. UFO hunter Toby Lundh saw an UFO just outside the space station earlier this year. He was monitoring the live feed on his laptop when he spotted the UFO.
