Bill Kaysing, analyst and engineer at the company that designed the Apollo rockets said he was convinced that the Moon landing was impossible. Some of his reasons include missing dust on the foot pads of the lunar lander upon arrival, or not being able to hear the astronauts’ voice with a running engine in the background. He believed that technology could not make it possible back then to transport humans to the Moon, therefore he made the conclusion that the landing must have been set on Earth, in the Nevada Desert to be precise. According to his belief, the US military’s base Area 51 seemed to be the perfect location to imitate the Moon landing, as it was a heavily guarded, top secret area. 
he most well-established filmmakers had been mentioned for helping in directing and writing the hoax, such as Stanley Kubrick, Disney or Arthur C. Clarke. The movie Capricorn One only fuelled this hoax, by showing a staged fake landing on Mars. Clearly, these accusations have been proven wrong by the evidence the Apollo astronauts have brought back, including moon rocks samples and lunar ground. 

Hoax believers have the most popular conspiracy theories including ‘missing stars’ in the sky, the flag waving while being erected even though there’s no wind, inconsistency in the direction of the shadows on the pictures, artificial looking light, and ‘missing’ blast crater under the lunar module yet visible footprints. There are scientific explanation to all the doubts hoax believers have. According to space historian John Hogsdon “Faking a staged Moon landing would have been much more difficult than designing a system and actually going to the Moon.”
