Kenneth Alfred Ham (born 20 October 1951) is an Australian Christian fundamentalist, young Earth creationist, apologist and former science teacher, living in the United States.

He is the founder, CEO, and former president of Answers in Genesis (AiG), a Christian apologetics organisation that operates the Creation Museum and the Ark Encounter.

[7][10] In 1977, Ham began teaching at a high school in Brisbane, where he met John Mackay, another teacher who believed in young Earth creationism.

[12] As CSF's work expanded, Ham moved to the United States in January 1987 to engage in speaking tours with another young Earth creationist organisation, the Institute for Creation Research (ICR).

[14] From the time AiG was founded, Ham planned to open a museum and training centre near its headquarters in Florence, Kentucky, telling an Australian Broadcasting Corporation interviewer in 2007, "Australia's not really the place to build such a facility if you're going to reach the world.

"[17][18] In a separate interview with The Sydney Morning Herald's Paul Sheehan, Ham explained, "One of the main reasons [AiG] moved [to Florence] was because we are within one hour's flight of 69 percent of America's population.

[29] In May 2007, Creation Ministries International (CMI) filed a lawsuit against Ham and AiG in the Supreme Court of Queensland seeking damages and accusing him of deceptive conduct in his dealings with the Australian organisation.

Conference organiser Brennan Dean stated Ham had made "unnecessary, ungodly, and mean-spirited statements that are divisive at best and defamatory at worst".

"[35] The disinvitation occurred after Ham criticised Peter Enns of The BioLogos Foundation, who advocated a symbolic, rather than literal, interpretation of the fall of Adam and Eve.

"[40] Ham said that publicity generated by the debate helped stimulate construction of the Ark Encounter theme park, which had been stalled for lack of funds.

[43] According to Ham, he was inspired by his father, also a young Earth creationist, to interpret the Book of Genesis as "literal history" and first rejected what he termed "molecules-to-man evolution" during high school.

Filmmakers Monica Long Ross and Clayton Brown followed the story line of a "religious organisation creating their own alternative science in a legitimate looking museum.
