The Old Testament is four different books that are melded together in a sloppy way. Scholars have taken over one hundred years figuring it out.
Also the Bible has been edited by people throughout history. It is easy to see by the threats made at the start of John's Revelations. Where he threatens any false scribes if they change his words they will be struck by the bad shit he was talking about. No reason to say these words if scribes did not change shit whenever they wanted.
Another in the New Testament. In Romans where there is a part that says God gave you your leaders and if you resist them and revolt you are going against God. Do you really think a man did not write that shit to make people sheep?
