This guy is some kind of liar. He seems to know enough science to know he is telling lies. The reason is he believes these are good lies (the way Trumper leaders do). This is a lie that will bring people to God, and they will behave better, and the lies will make a better world. The ends justify the means.
He says there were no fish on the ark. The big question is, if there were dinosaurs on Noah's ark, why does the word "dinosaur" not appear in the Bible? The story goes that God sent the young, small dinosaurs onto the ark, along with pairs of all the other animals. They pretend to believe the world was created 6,000 years ago, and their idiot followers really believe it. Why not? There is a $100 million "Ark Encounter" in Kentucky. They are deadly serious about this. The flood was 4,000 years ago. After the dinosaurs came off the ark, along with the modern animals, dinos went extinct soon after. They believe scientists don't know how to date fossils and rocks, or how to count tree rings or ice layers.
See the video where Bill Nye debates Ken Ham about the Ark Encounter delusion. Bill tells Ken he "betrays his intellect."
