Bill Nye the Science Guy spoke out this week against parents who teach their children creationism.
In a video that appeared on the website Big Think, Nye said that denial of evolution was unique in the United States and that teaching creationism holds the country back.
"Evolution is the fundamental idea in all of life science, in all of biology," said Nye in the video.
"It's analagous to trying to do geology without believing in tectonic plates."
"You’re just not going to get the right answer. Your whole world is just going to be a mystery instead of an exciting place,” he added.
Since his television show, Nye has advocated for science education and created a 13-part series on controversial scientific topics called "The Eyes of Nye."
ABC News reported that Nye made a three-stop tour in New Hampshire this summer supporting President Obama's science efforts while advocating for better science and math education.
Nye has said that in a few centuries, creation likely won't exist anyway given the lack of evidence for it, reported Today.
Nye – a mechanical engineer by trade - hosted the popular "Bill Nye the Science Guy, which aired on PBS Kids from 1993 through 1998.
