Johan Huibers Johan Huibers

If the end of the Mayan calendar signals a Biblical-sized flood, one man will be really prepared.

After 20 years, Johan Huibers has finished building a full-scale Noah's Ark, People reports.

The Dutch man used the Bible as his guide, converting cubits to modern measurements. His Ark is 427 feet long, 85 feet wide and 75 feet high.

Which shows have been renewed and which have been canceled?

Still, Huibers' Ark has nothing to do with a specific impending date. "I had a call from American television," he told the Associated Press. "This has nothing to do with the end of the Mayan calendar." Instead, he says, it's about what the Bible prophesizes. "I want to make people question that so that they go looking for answers," he says.

The Ark is currently home to a small petting zoo, a restaurant and a movie theater.
