Ken Ham

Kenneth Alfred Ham is an Australian-born Christian fundamentalist and young Earth creationist living in the United States. He is president of Answers in Genesis, a Creationist apologetics organization that operates the Creation Museum and the Ark Encounter.
Ham advocates Biblical literalism, believing that the Book of Genesis is historical fact and the universe is approximately 6,000 years old, even though scientific evidence shows the Earth is about 4.5 billion years old and the Universe about 13.8 billion years old.
