Truth. It's a special kind of intellectually lazy stupid that I particularly loathe. It's a dangerous, malignant stupidity, which betrays an intentional ignorance that is impossible for me to comprehend.
There are ~ 900 described species of dinosaur (not counting birds). The ark was supposedly ~ 440×72×43 ft. I've excavated a single sauropod sacrum (middle hip bone) that was 10 feet wide by itself. The whole animal would have been around 100 feet long and 50 tons. There are probably at least a dozen known dinosaur species in this size range. There are many, many other stupidly huge species as well.
It's like someone saying they put the actual Mt. Rushmore in their pocket for show and tell. If someone went around insisting on that, we'd institutionalize them, but we're letting someone that stupid and intellectually dishonest be 2 heart beats from the Presidency.
This really is the dumbest timeline.
