Well, as far as we know, yes. Now, the creationists obviously think otherwise, as seen in many different ministries, but where is their evidence? Creation Science Evangelism says that cryptozoology (the study of creatures like Bigfoot and the Loch Ness Monster) is proof. How so? In the Congo, home of thick swamps and jungles, natives say that prehistoric creatures still live. Now, as much as I’d like that to be true, it isn’t evidence for creationism. Why? Because there is no obvious statement in the Bible that dinosaurs lived with man. That’s partially because the term dinosaur wasn’t invented until the 1800s, but also because dinosaurs and man did not coexist. I know, I know, the Book of Job with Leviathan and Behemoth, but to be honest, the “tail like a cedar” thing doesn’t just point to a sauropod. For instance, look at the Nile crocodile. Some specimens can grow to be over twenty feet long, like the infamous Gustave, and their tails are thick and long. And there’s the fact that animal and plant species go extinct every day, so it’s possible that an unknown creature could have been mistaken for Behemoth. I used the computer game Spore to create a Behemoth:
But the crux of the extinction question comes in whether or not dinosaurs went extinct at any point. Now, the most popular theory involves a massive comet hitting the earth, and we have found large craters in the Chicxulub region that are evidence for that theory, but there are several others, which include but are not limited to: ice ages, plagues, volcanic activity, and others. And while living dinosaurs would be totally awesome, the odds are against it, no matter how much Sir Arthur Conan Doyle you read.
