Quote:Snelling is a prominent young-Earth creationist. For years, he has given lectures, guided biblical-themed Grand Canyon rafting tours, and worked for the nonprofit Answers in Genesis. (The CEO of Answers in Genesis, Ken Ham, is also behind the Creation Museum and the Ark Encounter theme park.) Young-Earth creationism, in contrast to other forms of creationism, specifically holds that the Earth is only thousands of years old. Snelling believes that the Grand Canyon formed after Noah’s flood—and he now claims the U.S. government is blocking his research in the canyon because of his religious views.
