Bill Nye is set to debate evolution with the founder of Kentucky's Creation Museum on Feb. 4, and the Science Guy is clear about what he thinks of creationism.

It frightens him.

On Jan. 21, Nye talked with HuffPost Live's Josh Zepps about why he feels so strongly about dispelling the notion that creationism is a reasonable alternative to evolution.

"It's a deep concern," Nye said. "If the United States produces a generation of science students who don't believe in science, that's troublesome."

The debate has drawn criticism from secular advocate Dan Arel, who wrote that "scientists should not debate creationists. Period."

While Nye acknowledged that he probably won't be able to change any creationist's mind, he said it made sense to challenge creationism in a public forum.

"I want to show people that this belief is still among us. It finds its way onto school boards in the United States," he said.
