But, again, they’ve got answers. There are models and plans and layouts of the vessel. You can walk through a part of the hull. There’s biblical carpentry and weather reports. And the dinosaurs are on board. (They were probably small ones, the museum helpfully adds.) But recently scientists found a new giant rat and a fanged frog in Papua, New Guinea, so now some Noah-ists have to redesign the amphibian quarters.
