The hacker collective Anonymous has claimed NASA is close to confirming alien life – and conspiracy theorists are going crazy.

In a video shared on YouTube last week, Anonymous cites passages of recent talks at NASA which seem to support the idea of extra terrestrial life.

The person posing as Anonymous in the 12-minute video said: "Mankind has already made contact with aliens, and not just little micro-organisms floating inside a massive alien ocean, but [instead] advanced alien civilisation.

"Professor Thomas Zurbuchen [of NASA] said our civilisation is on the verge of discovering evidence of alien life in the cosmos, taking into account all of the different activities and missions that are specifically searching for aliens.

"We are on the verge of discovering unprecedented evidence."

However, Professor Thomas tweeted last night to say these claims are false.

Taking to the social media site, he said: "Contrary to reports, there's no pending announcement from NASA regarding extraterrestrial life.

"Are we alone in the universe? While we do not know yet, we have missions moving forward that may help answer that fundamental question."

Many are claiming that the Anonymous video is just a bunch of old videos looped together.

Yahoo claims: "It’s likely just a looped clip of a previous video being reused for the umpteenth time."
