As we celebrate the 40th anniversary of the first moon landing, there are still conspiracy theorists who think it was all an elaborate hoax. Some maintain Neil Armstrong walked down a ladder and uttered "It's one small step for man, one giant leap for mankind" was shot on a Hollywood soundstage and beamed to a gullible world.
One documentary making the rounds on the Internet claims famed director Stanley Kubrick was recruited to create and direct the iconic footage.
A 2001 FOX television show called "Conspiracy Theory: Did We Land on the Moon?" helped perpetuate the myth. In response to that show at the time, NASA's Dr. Tony Phillips said, "The best rebuttal to allegations of a 'Moon Hoax,' however, is common sense. Evidence that the Apollo program really happened is compelling: A dozen astronauts (laden with cameras) walked on the Moon between 1969 and 1972. Nine of them are still alive and can testify to their experience. ... [And] Apollo astronauts brought 841 pounds of Moon rock home to Earth."
As far as those rock samples, it is universally accepted by scientists that they did not come from our world. And no one involved in the so called hoax -- and it would have to be hundreds of people to pull it off -- has ever come forward to tell their story.
But this seeming mountain of evidence has not stopped conspiracy believers, including Bart Sibrel, a filmmaker who made the movie "A Funny Thing Happened on the Way to the Moon."
He famously cornered Apollo 11 astronaut Buzz Aldrin in 2002, calling him "a coward and a liar." Aldrin responded by punching Sibrel in the face. Watch the confrontation here:
