Your first point makes no sense for multiple reasons. One, you have no right to judge what God's word should look like. By which I mean, you are applying your own standards to pass judgement on something of which you can know nothing. Two, I don't know where you got the idea that God wrote the bible. I've never heard that theory. The story actually goes that the bible is God's word, as written by humans. As such, it is prone to what you call "errors & contradictions".

Your second point is your opinion and hasn't actually been proven by historians. You can claim it has, but historians aren't agreed on what you are saying.
