Yes, and these books were produced at a time when science had yet to flourish and superstition was rife. If they were written much later they would be very different.
They purport to be from God but wouldn't this deity have some concept of what we now take for granted in our knowledge? I'm not trying to argue they don't exist but I may be more open to an argument that little was given to man and a lot he improvised with based on the knowledge levels of the time.
