Over a half of all Russians believe that US astronauts have never been on the Moon and that the US authorities and NASA covered up this fact by forging proof of moon landings, a new poll shows.In the recent survey titled "Science and society: authority and trust" experts of the Russian state-run public opinion research center VTSIOM wrote that 57 percent of Russians currently think that the US claims of successful manned Moon missions are lies and that the documented proof of these missions was forged. Only 24 percent of respondents said that they believed that the manned Moon missions were real.Researchers also specified that 65 percent of those who think that the US authorities are lying about the moon landings have secondary education.However, Russians are not only suspicious about the NASA moon missions.When facing the question if the scientists possessed some "objective knowledge" about the reality the Russian public again split into almost equal parts: 42 percent agreed that this was true while 41 percent said that in their opinion the scientists who claimed this weren't telling the truth, albeit in good faith.As far as space aliens are concerned, 45 percent of the poll participants said that they believed in the existence of extraterrestrial civilizations and 42 percent think that aliens either don't exist or for some reason prefer not to visit Earth and contact humans. 18 percent of respondents said that in their opinion the authorities were hiding proof of alien visits from the general public.
