On 4 February 2014, at the Creation Museum, Ham debated Bill Nye (also known as "Bill Nye the Science Guy"). The topic was the question "Is Creation A Viable Model of Origins?". The televised event drew over three million viewers. Ham's position was the world was created about 6,000 years ago. He also defended his position that all animals alive today descend from those aboard Noah's Ark. Nye argued that radioisotopic and ice core data shows that Earth has existed for much longer than 6,000 years. He also added that using the Bible's description of the Ark it could not float. A number of experts were critical of the debate saying that it did not discuss important areas. At least one said neither did very well. An informal viewer's poll showed 92% thought Nye won the debate. However, "Debate is a tool for showing who's a better orator, not necessarily who's right. And Ken Ham is no mean orator, usually," noted the National Center for Science Education, a not-for-profit membership organization that defends the teaching of evolution and climate science."
