SweetSavour, it is not that they automatically think behemoth and leviathan mean dinosaur. Keep in mind, that the word dinosaur was created by Richard Owen in 1841, stands for terrible lizard. Anyway it is not just based on that but if you look closely at the description for behemoth, it is not talking about an elephant or a hippopotamus. Leviathan can sometimes be Satan but it could also be a dinosaur, some have said a crocodile but I don't quite buy it. Plus there is evidence for it probably being a dinosaur because there are archaeological images of petroglyphs that have dinosaur-like motifs found in Peru and other places and there also eyewitness accounts of people who have seen dinosaurs. There is also the grave of a person named Bishop Bell and if you look closely there are pictures that he did that have been found to be anamotically correct with many of the species of dinosaurs today, like a long neck sauropod and a horned ceratopsian. But again, this is the information that the evolutionary scientists and the rest really do not want you to know, so it usually is not mentioned or they say they have debunked it or stuff like that. Also, when one uses the Huffington Post you are going to get an evolution-based argument or they will misquote someone. So while there are cases to use the Huffington Post, it is usually not a good idea to use them. So after watching that, check out the creationist's site and not just what other people say about him or falsehoods that are said about him or are attributed to him. Now, leviathan could be a marine reptile or dinosaur and there have been reports of such a creature in the Congo. The verses are not vague and I don't see a stretch. Just read them and then ponder the description, then imagine what the thing being described looks like. Since in the KJV, they will use the term dragon to signify some kind of reptile, like a dinosaur or something around those lines. I personally don't believe in an old earth and have my reasons but I also don't quite believe in a young earth either and I have my reasons. But you are free to have your opinion and views.
