The creationist charlatan, Ken Ham, who is the perpetrator of the Ark Park is using none of the methods used by science. Ken Ham is a part of the religious extremist AIG cult. Here is a part of their ''about'' section of the website.The creationist behind that attraction is using the same method that the Darwinians use in their own museum attractions: Put together a model based on their ideas of what the dinosaur era looked like, and expect people to accept it because they "see it with their own eyes."

Our Message
Answers in Genesis is an apologetics (i.e., Christianity-defending) ministry dedicated to enabling Christians to defend their faith and to proclaim the gospel of Jesus Christ effectively. We focus particularly on providing answers to questions surrounding the book of Genesis, as it is the most-attacked book of the Bible. We also desire to train others to develop a biblical worldview and seek to expose the bankruptcy of evolutionary ideas and bedfellow: a “millions of years old” earth (and even older universe).
AiG teaches that “facts” don’t speak for themselves: they must be interpreted.
As you know, (being a card carrying member?), they are charlatans who announce their bias. AIG requires their cult members to adhere to 'statement of faith' that facts and the truth are secondary to their fundamentalist agenda. They provide no science, they promote dogma.
To believe the planet us 6,000 years old, that people in buckskin outfits used to frolick with dinosaurs and that an Ark cruised the oceans just a few thousand years ago is delusional and dangerous.
