In a radio interview on Friday, Creation Museum founder Ken Ham attacked evolution as a “religion” that has “brainwashed” its adherents into thinking that they are observing a scientific theory.

Ham, a Young Earth Creationist, criticized Christians who believe in evolution by touching on the Creationist talking point that the Bible is the only eyewitness account of the history of the world.

“A lot of these Christian leaders, when they say the word ‘day’ [in Genesis] can’t mean an ordinary day because of science, it’s not observational science they’re referring to, it’s man’s historical science. In other words, man’s beliefs about evolution and millions of years,” Ham told VCY America’s Crosstalk.

“They’re taking man’s religion of millions of years and saying, ‘That’s why you can’t believe what the Bible says.’ If the word ‘day’ in Genesis 1 means an ordinary day and you say it can’t because of what man is saying, then you’ve just said God’s word is fallible and it’s man’s word that is infallible. No, it’s the other way around.”
