The bible is not a history book, its not a science book, its not a book on politics, and its definitely not the only book on the shelf.

It is a book that does have a few of those things included in it (very few). However the intent/purpose of the bible is to explain Mankind, God and the relationship between the two.

Genesis is not literal. It is allegory, a story - sort of a prolog that tells us 'what went on before' to get us ready for the rest of the collection of books.

No Dinosaurs are not in the bible, nor are the 4.5 billions of years that went on before the first humans arrived on earth. There was no Adam and No Eve as named people. There is the Adam - humanity.

Dinosaurs are not important in the explaining of what mankind is and what God is and what the relationship between the two is. Nor is stem cell research part of this subject, nor is exoplanetary subjects, or chemistry, or physics or a lot of other things.

Mankind, God and the relationship between the two is the only purpose of the bible.

Unfortunately too many people have been taught that the bible is supposed to do more (erroneously). And have fallen into the terrible trap of trying to weight the whole world against the bible, either to justify their belief or to disprove the belief of others.
