Unearthed footage has once again been circulated on social media showing the moment Buzz Aldrin punched a conspiracy theorist who claimed the astronaut never stepped foot on the Moon.

It has been 51 years since the July 20 Apollo 11 Moon landing in 1969, an event that marked not only mankind's "giant leap" in space travel, but perhaps mankind's greatest ever accomplishment.

However, this also means 51 years have passed for conspiracy theorists to outright deny that the Apollo 11 mission - which was crewed by astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins - was faked.

Now, it is only understandable that a person would get deeply frustrated if people continued to repeatedly deny their biggest achievement - and that's exactly what happened to Buzz Aldrin when he was confronted by a Moon landing denier back in 2002 outside a Beverly Hills hotel.

In a resurfaced video shared to Twitter by user Rob Harvey, Aldrin can be seen becoming increasingly annoyed by conspiracy theorist and filmmaker Bart Sibrel, who repeatedly orders the American icon to put his hand on the Bible and swear that he walked on the Moon.

In the clip, Aldrin can be heard saying to Sibrel: "Will you get away from me?!"

But Sibrel continues, branding the astronaut - now 90 years old - a "liar and a coward".

Eventually, Aldrin has heard enough and lands a swift right-hook straight into Sibrel's face.

Harvey captioned the clip, "Buzz Aldrin you gangster", and despite being 18 years old, it has already amassed over 1.4 million views in just four days (as of this writing).

In an interview with The Sun last year, Sibrel stated: "This conspiracy is the most symbolic of government arrogance. It was totally 100% contrived - none of it is true - yet they held ticker-tape parade for these guys and gave them congressional medals of honor.

"It was a needless lie really just done for no reason other than arrogance and greed. And it makes a sucker out of every American who believes it is true."

Sibrel added: "What the United States government is claiming is that they sent astronauts one thousand times farther than they can send them today, with fifty years older technology and on the very first attempt, with all of NASA containing one-millionth the computing power of a cell phone.

"The alleged moon landings are the only technological claim in the entire history of the world that was not far surpassed fifty years later."

And as you can see by the recent Twitter responses to the video, the debate over the Moon landing is destined to continue:
