Bryan Fischer of the American Family Association has opinions (usually reprehensible) about Muslims, abortion, gay marriage — the usual sticking points for far-right evangelical Christians. Now he’s trying his hand at paleontology, but it’s safe to say that his claims aren’t peer-reviewed.

On his Focal Point radio program this Tuesday, Fischer tried to explain why the dinosaurs went extinct from a young earth creationist’s perspective. Fischer takes the bible literally, which forces him to hold the belief that the earth is around 6,000 years-old. This belief system has led him, and others like him, down a rabbit hole that concludes humans coexisted with dinosaurs.

Despite his belief that dinosaurs were present on Noah’s Ark, Fischer tried to explain why they went extinct anyway by using a story about the extinction of a prehistoric rhino species as an example — the “Siberian Unicorn” rhino went extinct about 40,000 years ago due to diminished grasslands as a result of the ice age.
