This question can be answered the same way we can explain why the words “telephone” and “computer” are not in the Bible: It wasn’t invented yet. The King James Version of the Bible was written in 1611, but the word “dinosaur” was not invented until 1841, which was 230 years later. However, the KJV does include a certain word called “dragon,” and when put in the context of certain Biblical passages, “dragon” describes the characteristics of dinosaurs. Cultures around the world have/had words used to describe dinosaurs. You can see a listing of those words here.
Although secular scientists, and the majority of people for that matter, believe that dinosaurs died out millions of years ago, there is much supporting evidenceto show the contrary. What kind of evidence would one expect to find if dinosaurs and man co-existed? Here are some non-biblical accounts of dinosaurs existing with man:
A Sumerian story dating back to 2000 BC or earlier tells of a hero named Gilgamesh, who, when he went to fell cedars in a remote forest, encountered a huge vicious dragon that he slew, cutting off its head as a trophy.
When Alexander the Great (c. 330 BC) and his soldiers marched into India, they found that the Indians worshipped huge hissing reptiles that they kept in caves.
China is renowned for its dragon stories, and dragons are prominent on Chinese pottery, embroidery, and carvings.
England and several other cultures retain the story of St. George, who slew a dragon that lived in a cave.
There is the story of a tenth-century Irishman who wrote of his encounter with what appears to have been a Stegosaurus.
In the 1500s, a European scientific book, Historia Animalium, listed several living animals that we would call dinosaurs. A well-known naturalist of the time, Ulysses Aldrovandus, recorded an encounter between a peasant named Baptista and a dragon whose description fits that of the small dinosaur Tanystropheus. The encounter was on May 13, 1572, near Bologna in Italy, and the peasant killed the dragon.
