Any animal with a tail as huge and strong as a cedar tree is probably a dinosaur. If the writer of Job knew of a dinosaur, then the evolution position is wrong, and man saw dinosaurs. The next chapter of Job describes another huge, fierce animal, a sea monster named Leviathan. It was not a whale or crocodile, because the Hebrew language had other words to describe such animals. Consider the many dragon legends.
Most ancient cultures have stories or artwork of dragons that strongly resemble dinosaurs.
Dragons were generally evil and destructive. Every country had them in its mythology. The simplest and most obvious explanation for so many common descriptions of dragons from around the world is that man once knew the dinosaurs. Because dinosaur bones are found among other fossils, dinosaurs must have been living when the flood began. There are dozens of other dinosaur extinction theories, but they all have recognized problems.
