What was the first book ever created?

The Holy Bible...I think.

Actually, The Bible was not the first book. Books have been in existence for thousands of years. Also, how you define "the Bible" depends changes the equation.

The King James Version, which one version many people consider to be the actual Bible (matter of opinion) wasn't in existence until the early 1600s, when is was transcribed by King James scribes.

The Gutenberg Bible, which was the first Bible to be printed on a printing press, was printed in the 1450s.

Other versions existed before that, but they are all translations of the orginal letter and manuscripts from the writers, and for that matter, there were many letters and manuscripts written by some of the same people that were not included in many of the versions of the Bible that are in existence.
