InfoWars host Alex Jones has been known to make some outlandish and downright strange accusations when it comes to conspiracy theories. His craziest episode might just be a recent one in which a former CIA guest claimed that NASA is running a child slave colony on Mars. A claim that NASA, as you might imagine, was quick to refute.

NASA spokesperson Guy Webster told The Daily Beast in a statement. “There are active rovers on Mars. There was a rumor going around last week that there weren’t. There are…. But there are no humans.”

This whole incident came to a head after Jones had Robert David Steele, a former CIA officer, on his show earlier this week. Steele made the wild allegation that NASA was shuttling children on a 20-year journey to Mars in order to make them slaves.

“We actually believe that there is a colony on Mars that is populated by children who were kidnapped and sent into space on a 20-year ride,” Steele said on Infowars. “So that once they get to Mars they have no alternative but to be slaves on the Mars colony.”

His only proof, or lack thereof, of such a preposterous activity taking place was word of mouth from a supposed “high-level NASA engineer.”

“Look, I know that 90 percent of the NASA missions are secret and I’ve been told by high-level NASA engineers that you have no idea,” he told Jones. “There is so much stuff going on.”

Jones’ Infowars show has peddled some of the most bizarre conspiracy theories out there. Jones is probably best known for his controversial claim that the 2012 Sandy Hook Massacre, in which 20 children and six adults were murdered, was nothing more than a mere hoax.

Jones is also a firm believer that 9/11 was an inside job orchestrated by the government to keep the American people oppressed.

None of his claims so far have been proven to be true. And with NASA publicly denying the child slave colony, it’s safe to say this claim has been debunked as well.
