Ken Ham sees a parallel between the time of Noah in the biblical book of Genesis and today’s growing secularization of American culture.

So perhaps it makes sense that Ham’s Christian apologetics ministry, Answers in Genesis, has built an ark 510 feet long, 85 feet wide and 51 feet high, based on measurements God gave Noah, in cubits, in the biblical account of the great flood.

But whereas only eight people in Noah’s family climbed aboard the biblical ark, when on Tuesday the rain began to fall, as if on cue, more than 8,000 people got a first look inside the full-scale reproduction at the Ark Encounter.

The ark and the 800-acre theme park officially opened to the public Thursday in northern Kentucky, 45 minutes from another Answers in Genesis attraction, the Creation Museum.

Ham called the Ark Encounter’s opening “a historic event in Christendom” at the ribbon-cutting and preview Tuesday and predicted that it would become “one of the greatest Christian outreaches of this era of history.”

The park’s centerpiece has three decks of exhibits explaining Answers in Genesis’s views of the biblical flood account and life-size figures depicting what an existence on the ark might have been like for Noah and his family — an extravaganza Ham described as “beyond Hollywood.”

The park also has a two-story restaurant, aerial zip-line cables and the Ararat Ridge Zoo with goats, ponies, emus and other animals. The next phase of park construction is likely to include a walled city “that takes you back to Noah’s day” with shops, restaurants and street performers that visitors will walk through as they approach the ark, said Michael Zovath, chief action officer for Answers in Genesis and project director for the Ark Encounter.

But the Ark Encounter is “not just for entertainment,” said Ham, president and chief executive of Answers in Genesis.

It’s to “proclaim God’s word and the gospel,” he said. It’s meant to show — in keeping with the Answers in Genesis ministry’s focus on such issues as creation, evolution, science and the age of Earth — that the biblical flood account is historic and that the Bible is historically and scientifically true.

“When people say, ‘What are you really doing here? What statement are you making?’ well, you know, in a world that we see becoming very secularized before our eyes, it’s really time for Christians to do something of this size, of this quality, that competes with the Disneys and the Universals to get a message to the world,” he said.

That’s a mission and an interpretation of scripture that the park’s first visitors celebrated at the preview event Tuesday, but it’s also a retelling that critics call inaccurate at best and potentially harmful at worst.

“We share with the people at the Ark Encounter a belief in the Bible, but Answers in Genesis and Ken Ham do not speak for all Christians,” said Deborah Haarsma, president of BioLogos, a Christian ministry promoting an evolutionary understanding of creation.

Rough waters

The park’s opening day — July 7 or 7/7 — was chosen because Genesis 7:7 reads, “And Noah and his sons and his wife and his sons’ wives entered the ark to escape the waters of the flood.”

Employees have been working six days a week since April to finish by that date, Zovath said. Lighting and animal sculptures (eventually, the ark will hold 200) remain to be finished, and the animal sounds and music that boom through the wooden structure have not been finalized, according to Patrick Marsh, vice president of attractions for the Ark Encounter.

That timeline isn’t the park’s only challenge. In 2014, the theme park was awarded, then denied, Kentucky tax incentives worth an estimated $18 million over 10 years. The incentives were lost because Answers in Genesis requires employees to sign a statement of belief, but in January, it won a lawsuit to have them restored.

The first phase of construction at the park cost $100 million (total costs will reach more than $150 million), funded through bonds and $33 million in private donations, according to Ham. The Answers in Genesis president is adamant that no taxpayer funds were used for construction. Rather, he said, tax incentives will provide rebates on sales tax generated by the park now that it’s opened.

During a news conference attended by cheering supporters, Ham said he thought the park was being singled out because of prejudice against Christians.

Tri-State Freethinkers, an area group advocating the separation of church and state, turned out for the park’s opening to protest its “anti-science” mission and “discriminatory hiring practices,” as well as what the group calls the immorality of the biblical flood account, according to its website.

Biblical worldviews

What the ministry teaches — sometimes referred to as “young Earth creationism” — is that Earth is about 6,000 years old, that humans once lived alongside dinosaurs, and that the six-day creation and flood accounts found in the first 10 chapters of Genesis are literally, historically true.

That reading of Genesis is important because, Ham said, “when you take away the foundation of the absolute authority of the word of God, then anything goes. . . . In other words: Who draws the line?”

A 2015 study by the Pew Research Center found that 65 percent of American adults believe that humans and other living things have evolved. That number jumps to 98 percent among members of the American Association for the Advancement of Science, the survey found.

The vast majority of scientists say that Earth is more than 4 billion years old, that there never was a flood that covered the whole planet and that the variety of species today could not have descended from the animals on the ark. (Ham maintains that as many as 1,400 “kinds” of animals were brought aboard the ark, with changes within those kinds over time leading to the diversity of animals we see today.)

On the ark’s third deck, a sign in an exhibit about an ice age points out that creationists and evolutionists look at the same evidence and draw different conclusions. The sign explains the difference between “the evolutionary worldview” and “the biblical worldview.”

But there’s more than one “biblical” worldview, say Susan L. Trollinger and William Vance Trollinger Jr., professors at the University of Dayton and co­authors of the book “Righting America at the Creation Museum.”

“Young Earth creationism holds sway in fundamentalism and in a good part of evangelicalism,” said William Trollinger. But it was popularized among Christians in 1961 with the publication of “The Genesis Flood” by the late Henry Morris and by John Whitcomb, who attended Tuesday’s ribbon-cutting.

Haarsma said she worries that Answers in Genesis builds an atmosphere in which Christians feel they have to choose between Bible and science, between belief in God and in the natural sciences.While Ham points to anecdotes of people turning to faith after confronting the evidence from Answers in Genesis, Haarsma said BioLogos has stories of people turning away after confronting evidence to the contrary.

At BioLogos, she said, “we see the natural world as God’s creation, so we can celebrate the Big Bang and evolution as discoveries about how God created this world.”

Flood of guests

Those at Tuesday’s ribbon­cutting and park preview were either members of the media or supporters who had made donations for the construction of the Ark Encounter.

America’s Research Group estimated the park could attract as many as 2.2 million visitors in its first year. ARG’s research also indicates that more than 40 percent of those visitors may not even be Christians.

“Even if they don’t share our biblical view,” Ham said, “they can’t help but be impressed by the structure, the craftsmanship, the attention to detail in the world-class exhibits inside. And — who knows? — maybe they’ll be challenged to even talk about the Bible as we do.”

The animal sculptures were a hit with Michigan couple Holger and Lindsey Spiewak’s seven children. They especially liked the dinosaurs, they said.

And 8-year-old Merrick Spiewak said, “I think it’s really cool because the people looked really real.”

The Spiewak family has been following the ark’s construction for the past seven years, Lindsey Spiewak said, but “to see it come to life and be real life is amazing.”

“We came up on the hill where the ark was sitting,” she said. “It just took my breath away, and I had tears in my eyes because, wow, this was real. It’s a piece of history. I just think it’s so cool.”

Steven Gutierrez, who came to the park from California with his wife, Veronica, and their young daughter, Apphia, said he discovered Answers in Genesis’s ministry a few months after becoming a Christian. Gutierrez, who had lots of questions, said that he found its resources helpful and that he hoped the exhibits aboard the ark would help others.

“If there are people who are skeptical and confused,” he said, “a lot of their questions could be answered just by walking through the exhibits.”
