Because Genisis is telling us what HAPPENED. Deuteronomy is telling the JEWS what to DO.
We don't accept your answer becasue THEY MAKE NO SENSE.
I see. So you are now a Creationist? And should the Jews continue to do as they were told by the Lord? The laws against homosexuality, adultery, murder and stealing should or should not stay and exactly what logic do you use in determining what to obey or not?
Then you say, " I have told you over and over and over again that unless one has the Holy Spirit residing within" and once again, you've got some splainin to do, You evidently must have "spiritual discernment" to understand the bible (which I THOUGHT I used to have but according to you I did not). So exactly how does one go about getting this discernment without having discernment ? As a former militant atheist yourself, i'm sure you can tell us a logical way to gain discernment when you think it is all BS, I await.
What the Jews do is between them and God. None of my business. When Christ died for our sins, all of the rules changed. While the Old Testament has instructions for the Jews, and it has history and wisdom for all, the only "rules" we have to abide by now are the ones Jesus gave us.
Your last paragraph is a bit difficult to decipher. What exactly are you saying *I* think is all BS?
But if you are asking how to get the Holy Spirit to come into your heart so you will have guidance in SPIRITUAL MATTERS, all you have to do is ask sincerely. And please note, I NEVER said one needs the Holy Spirit to understand what the Bible says. I said one needs the Holy Spirit for guidance in spiritual matters. There is a difference you know.
As for our answers not making any sense to you, well, perhaps if you ask for guidance from the Holy Spirit, you will understand.
But just who do *I* ask for guidance to understand your reasons for constantly insulting people of faith? Your flying spaghetti monster? 
Nah, I'll ask the Holy Spirit. And I've already gotten the answer. (And no, I won't share that answer here - you wouldn't like it.)
