If I were not a Christian, I would still enjoy the Old Testament literature very much. I would still understand how much it tells us about the ancient world, its customs, beliefs, etc. But I would not accord it any more honor than I do the Illiad. Of course, I am a fan of Homer, too...
Welcome to the forum Jane.
I don't think that there are many people here who would disagree with you. The OT is a complex, fascinating document, which speaks volumes about the customs and values of an ancient society.
Where I think you will find disagreement is if you present the God of the OT as representing values that most of us would embrace. I think that most of us who have read the OT find the God to be violent and petty.
