Ever wondered if lizard people are real? You're not alone. An incredible 12 million Americans not only believe lizard people exist, but they think these reptilians control politics. And this is just one of many surprisingly popular conspiracy theories. According to a 2013 poll conducted by Public Policy Polling, 51% of Americans believe there was a larger conspiracy behind JFK's assassination, making it the single most popular conspiracy theory. A surprising 14% believe in Bigfoot, and 7% believe the 1969 moon landing was staged. About 9% of Americans believe the government adds fluoride to our water, not for dental health reasons, but for something more sinister—some believe they do it to control the minds of the public.
