Ken Ham is the president of Answers in Genesis, an organization that operates the Creation Museum and the Ark Encounter, two well-known attractions in Kentucky. Ham is perhaps the country's best-known apologist for the idea that the universe is approximately 6,000 years old. In part because of his strong following in the fundamentalist and homeschool community, Ham has been the target of both favorable and unfavorable media attention. Ham has criticized other evangelical Christians who have a high view of biblical authority but who disagree with him on the belief that creation took place over six 24-hour days.
