Darek Isaacs, who wrote the book "Dragons or Dinosaurs," believes that dragons are real because they are mentioned in the Bible.
While it is true that the word "dragon" does appear in prophecies in the Books of Ezekiel and Revelations, it is generally accepted by most mainstream theologians that the word "dragon" is used as a metaphor.
Also, the Bible was written in Hebrew, Aramaic and Greek, so the word "dragon" may have been added in the King James (English) translation.
However, Isaacs appeared said on the program "Creation Today" and said that dragons are literal creatures, noted RawStory.com (video below).
“The Bible speaks about dragons. Our authority, everything we do we have to measure by the word of God, that is what I believe. So, we have to go to the Bible, and the Bible speaks about dragons. It speaks about dragons in the Old Covenant scriptures and in the New Testament." said Isaacs.
“...Here is the issue. If dragons in fact were entirely mythological, if they were a figment of the imagination, and if they never ever did exist, then God just compared our adversary to a make-believe creature that never existed.”
Isaacs also claimed that myths about dragons are based on the experiences that human beings had with dinosaurs 6,000 years ago.
However, Isaacs appears to want it both ways, claiming the Bible says dragons are real, but then adding that dragons were actually dinosaurs (not dragons) in myths.
