A number of different hoax claims have been advanced that involve conspiracy theories outlining concerted action by NASA employees, and sometimes others, to perpetuate false information about landings that never occurred, or to cover up accurate information about the landings that occurred in a different manner than have been publicized. Believers have focused on perceived gaps or inconsistencies in the historical record of the missions. The Flat Earth Society was one of the first organizations to accuse NASA of faking the landings, arguing that they were staged by Hollywood and based on a script by Arthur C. Clarke.[13]
