"Does God's word contain any errors?"
Woah! Hold up there. Who say's it's God's word?
I tell you what I see: A book, written by men, claiming that the entities called God and Satan exist. These men have also written some stories to back up this claim and these stories involve talking animals, magic, the sun stopping it's movement across the sky. etc. etc.
You can't prove something incredible by citing things that are impossible.
There is nothing more than this to prove the existence of Jehovah God and Satan. All other, non-biblical, proofs, could only ever prove the existence of A deity, not this particular deity. There is nothing to link the claims the bible makes with any other proofs.
To answer your question, No human has ever read God's word.
