8. Moon Landing
One that may not be as well known as conspiracy theories surrounding the assassination of President John F. Kennedy or the attacks of 9/11, but it is one that has been bandied around for a few decades at this point. Most people who were alive at the time were amazed and fascinated by man’s first landing on the moon on July 20, 1969. Since that time, some theories have been forwarded that claim the whole thing was a hoax and was simply all acted out for the cameras on a Hollywood-type stage. Proponents point to weird shadows on lunar photographs, a flag that appeared to be blowing in the wind and other alleged anomalies.
