A video showing a fleet of UFOs taking off from the moon was uploaded by Geri Vigil on YouTube on November 13 2016, and titled as "Large Group of UFOs Leaving the Moon". This video has received almost 18,000 views so far.

Alien theorists believe that the video points at the existence of the extraterrestrials living on moon. The belief, however, is rubbished by sceptics who say that it's a mere optical illusion.

The video shows various tiny bead-like structures leaving the bottom surface of the moon, which looks very luminous. 

Despite being described as being deceptive, many viewers believe it shows aliens departing from the surface of Earth's natural satellite.

Here's a link to the video:

Hilarious comments are being posted by viewers about the video. One of them said: "Those aliens were rooting for the establishment of the New World Order, but since Donald Trump won the elections, they lost hope and decided to just go home... that's what we are seeing in this video." Another comment by Talia Adagio1 stated: "I see the same effect in reverse on the right side, they look like they are landing instead."

Gary McKinnon, a former hacker, who has been convicted for hacking into NASA and US military-related data, too joined the debate. He believes it is an optical illusion. "There's a lot of footage of objects leaving the moon, as more people get better telescopes it's being observed more often," he told "This looks like far too many though, I think it must be visual artifacting." 

A photographer, John Biondo, too agreed with McKinnon, and said, "UFO's are NOT what you're seeing. It is a phenomenon seen anytime you look at the Moon's edge." He added: "I have lots of telescope time. You see this all the time, it's called Chromatic Aberration. (Google it) You see it more when the lens is out of focus as well, such as in this video." 

Scott C Waring, a UFO blogger, too commented on this video, saying that various Apollo astronauts have admitted to seeing UFOs on and around the moon. He also stated that we haven't been back to the moon since NASA's Apollo missions, which took place between 1961 and 1975, reported.

Various images of these 'UFOs' have been captured by NASA's International Space Station (ISS) too, but the debate regarding it being a deception or real thing has been going on.  

Numerous UFO sightings have been observed so far, here's a link to some of the most astonishing sightings which took place. You decide if it's real or just an illusion:
