Am I the only person to realise the bible is written by men for men and not god?

The sheer amount of contradictions in the bible purporting to come from the same source would rule out any possibility of there being a remotely omnipotent being behind it. Further, can someone please explain the amount of gratuitous violence supposedly ordered to be carried out agains various ethnic groups in the name of the Lord? Isn't S/He supposed to be a nice being?
