Like Jurassic Park and Jurassic World? Well, they’re great movies, but only artistically. Scientifically (and thus biblically), they’re dead wrong (pun intended).
Once a fossil or similarly buried object passes about 100,000 years, almost all its radioactive carbon is gone. Some secular scientists will argue that the fossils are contaminated from other sources, such as coal and diamonds, but the scientific procedures assure it against intrusion of foreign matter.
We could conclude dinosaurs could have been among us, but that’s for another post.
