Some people think birds are descended from dinosaurs. Yesterday's "Arlo and Janis" comic strip has Arlo chasing squirrels away from a bird feeder, than asking 3 little birds perched nearby, "What would cousin T-Rex think?"
To be fair, they say “around” 113 million years ago. So . . . give or take. But, yes, an arbitrary date assignment not based upon empirical science. The tracks are reasonable evidence of a global flood, as are whale fossils in deserts and oceanic fossils on mountain tops.
