The Greatest Conspiracy Theory of All Time Quick and easy responses to moon landing hoax claims, Jul 10, 2016
"Make a short list of important and spectacular historical events, and it’s clear that the Apollo Moon missions were unique in the way they were documented. There were no cameras at the Battle of Marathon. No NPR reporters at the French Revolution. The Mongol invasions came and went without a single press conference. Nor was their extensive print or web news coverage of the invention of the first stone tool or the first time a human created fire. Even most of World War II took place off camera.
By contrast, every step of NASA’s effort to get to the Moon was meticulously documented from within and without. This thoroughness left behind many thousands of documents, photographs, and audio/video recordings, as well as millions of typed and handwritten words. Artifacts, the tangible hardware, from lunar mission are currently on display in numerous museums around the world. And there is the Moon itself. Astronauts returned with more than 842 pounds (382 kilograms) of Moon rocks that have been shared and studied by scientists in many countries for decades. None of these experts have expressed doubts of the rocks’ origin.
Maybe NASA could have produced convincing video on a terrestrial sound stage that was good enough to fool non-experts. But why do it so many times? There were nine missions to the Moon, six of which landed. The Apollo 16 and 17 crews each spent three days there. Why? If this was all a daring PR stunt, why increase the risk of discovery with multiple missions? Why make it necessary for so many astronauts and ground personnel to lie and maintain the cover up? If this were a hoax, doesn’t it seem more likely that NASA would have faked one landing, had a big parade, and then promptly shut down the operation?"
