There is a series of people who believe that NASA faked all the Apollo Moon landings of 1960s and 1970s and they claim to have all sorts of evidence. This include the pictures taken by astronauts, engineering details, physics factors and testimonies by some of these astronauts. It has been claimed that all the Moon thing is fake and all this took place at Area 51 in Nevada desert.
Due to the Cold War pressure with the Soviet Union, NASA did not have the full capacity to go to the moon thus faking it all. I am still surprised by all these and i will dig and do research so i can come to my own conclusion of whether to believe or not.
