Creationists are up in arms about Cosmos: A Spacetime Odyssey, astrophysicist Neil deGrasse Tyson's science documentary television series, because they say the show does not present their beliefs alongside evolutionary theories.

Danny Faulkner, an astronomer who works with Answers in Genesis, a Christian ministry and its Kentucky-based Creation Museum, spoke out against the program Thursday on The Janet Mefferd Show. He took issue with many aspects of Cosmos' first two episodes, including its positive stance on biogenesis and its assertion that the universe is billions of years old.

"Creationists aren't even on the radar screen for them," Faulker said on the faith-based talk show. "They wouldn't even consider us plausible at all."

Cosmos has already been under fire from creationists for its stance on evolution, climate change and the Big Bang theory, but Tyson told CNN earlier this month that he believes the media should no longer give equal airtime to those who deny climate change and evolution in an effort to balance coverage.

Faulkner claimed the 13-episode series has a distinct "evolutionary bias," and agreed with Mefferd's concern that Cosmos doesn't even present creationism as an alternative theory.

"That was struck in the first episode where [Tyson] talked about science — how everything's up for discussion, it's all on the table — and I thought to myself, 'No, consideration of special creation is definitely not open for discussion'," he said.

A television station in Oklahoma was criticized for cutting to a news promo while Tyson spoke about evolution in Cosmos' premiere episode, but the later claimed in a tweet that this was a mistake.

Neither Fox nor National Geographic, which broadcast the show, immediately responded to a request for comment.

This isn't the first time creationists have bumped heads with the scientific community. TV personality Bill Nye debated Ken Ham, founder of the Creation Museum, on evolution last month.
