I find it hard to believe that dinosaurs ever existed. They were never mentioned and totally skipped in the holy books (Old Testament, New Testament, Qur'an) although these books do contain stories as old as it gets (to Adam and Eve, Noah, The Great Flood, and Ibrahim). How can we know dinosaurs existed?

    What about the behemoth? The wikipedia article mentions "Behemoth is commonly identified as possibly being a sauropod dinosaur" See en.wikipedia.org/wiki/Behemoth

    I know of nobody who claims that dinosaurs did not exist. Please find a notable example of this claim in order to make this an appropriate question. Apr 11, 2012 at 2:55

    If I'd seen that question I'd have voted against it. It opens up the door to questions like "Is there really a country called Spain?"; "Did Richard Nixon exist?"; "Is Obama a Christian?". Apr 11, 2012 at 3:16

    @SamIAm: Indubitably. I'm waiting for someone with a better grasp of that evidence answers before I try. I'm just trying to clumsily explain that Believer's counter-evidence has a bit of a mismatch with the theory, leading to non-sequiturs.

    The existence of thousands of dinosaur skeletons is incredibly convincing. What evidence could you imagine that would be more convincing? Apr 12, 2012 at 15:07

1 Answer 1


There is a whole science dedicated to the study of fossils, which we know puzzled mankind at least since 500bc:

In ancient times Xenophanes (570-480 BC) wrote about fossil sea shells indicating that land was once under water

Dinosaurs is a very broad term and refers to a group of animals of which we have bones and entire skeletons.

Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic period, approximately 230 million years ago, and became the dominant terrestrial vertebrates for 135 million years, from the beginning of the Jurassic (about 200 million years ago) until the end of the Cretaceous (65.5 million years ago), when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the close of the Mesozoic era. The fossil record indicates that birds evolved from theropod dinosaurs during the Jurassic, and consequently they are considered a type of dinosaur in modern classification systems.

You can visit most museums and see or touch some fossils them if that convinces you.

    But Wikipedia is not a sufficiently reliable source to be solely used in meeting Skeptics Exchange standards for a well-referenced answer. Could you please add references that are not wikipedia? :-)

    Wikipedia is good enough for high school level claims. These are all (I would defend) primary school* level... *According to my son who is in primary school and loves dinosaurs.

    @Believer: Can you find any mention of cats in the Koran or Bible?

    @Henry, Dinosaurs is the equation changer. It invalidates everything Quran and bible says. Because they lived for millions of years. If that is true, the Islamic theory of evolution (derived form Christianity) falls flat and almost everything it says is then wrong. Does it make sense?

    "I just have hard time believing it. For me it if I want to believe in it I must quit my religion." You are committing the "appeal to consequences" fallacy. Just because you don't like the consequences of a claim is not a reason to accept or reject it. You should base your decision on the preponderance of evidence.
