He holds a Master of Arts in Biblical Studies and a Ph.D. in Bible and Theology, both from the unaccredited Louisiana Baptist University. He is the author of six books about his explorations. Cornuke uses the Bible as a literal guide for his explorations, and gives it priority over secular and historical sources. James K. Hoffmeier describes him as "a former Los Angeles SWAT policeman and more recently a real estate agent" in his 2005 book Ancient Israel in Sinai: The Evidence for the Authenticity of the Wilderness Tradition. Cornuke claims to have discovered the anchors from the Apostle Paul’s shipwreck in Marsaskala, as described in the Bible's Book of Acts, chapter 27 — by searching the sea floor off the coast of Malta. His also made expeditions to Takht-i-Suleiman in Iran in July 2005 and June 2006, where he asserts that he found a rock formation approximately 400 ft long at elevation. Cornuke's search appeared on Fox News, CNN, and Good Morning America as well as others.
In 2002 Cornuke claimed to have found anchors from the biblical shipwreck of the Apostle Paul in waters near Malta. This claim has been disputed. In 2003 Christianity Today reported that the then U.S. ambassador Kathryn Proffitt sued Cornuke to stop the sale of his book after she arranged for the "Maltese government to pardon the fisherman." Proffitt contended that as part of the pardon arrangement and several other issues, Cornuke agreed to remain silent about the pardon and "to allow Proffitt and the Maltese government to edit the book. He would also be required to encourage tourists to visit ancient temples." According to some he did not keep his part of the agreement. A federal judge denied the request to hold up publication of the book since it was already released at the time. Even still, "what the Maltese government is apparently upset about, however, isn't that Cornuke's book was published without its permission, but that it claims that the shipwreck never happened in the traditional site on the northeastern tip of the island, now known as St. Paul's Bay."
Supporters of Cornuke claimed in June 2006 that Cornuke may have discovered Noah's Ark in a pile of dark-colored rocks on the Iranian Takht-e Suleiman or Mount Suleiman in the Alborz Mountains. Cornuke relies heavily on one eyewitness of Noah's Ark, Ed Davis, in which there are problems with him being in Iran let alone at this site when he claimed to see Noah's Ark in 1943. Even creationist geologists doubt whether the rocks viewed by Cornuke are petrified and are urging caution. The research team included Arch Bonnema, film producer of The Genius Club and other well-known Christian businessmen. John Morris, of the Institute of Creation Research, does not believe the rocks viewed by Cornuke are petrified or Noah's Ark. Even Cornuke himself isn't completely convinced that what he observed was Noah's Ark or even if it was petrified wood. Associates for Biblical Research also produced a 7,800-word paper about problems with the Cornuke site. National Geographic critiqued the rocks at the site.
