I freely admit that I don't know who wrote the Old Testament, who wrote it and when. There are lots of theories, but after researching this rather extensively I have found nothing close to definitive in terms of who the authors were and when and how and why they wrote it. What bothers me is that people are so willing to believe folk tales written by unknown ancient authors that are inherently implausible and often inconsistent. And I give some credence to the theory that a king or two may have been behind the first five books, as part of strategy to control his subjects. This is merely a theory, but if you read the such books, as I have done several times over the years, it makes a lot of sense The fact that no one really knows much about the authors and the circumstances suggests to me that "believers" should at least have some healthy skepticism. The Old Testament has some aspects that are positive and admirable and some that are not, and the fundamentalists have historically exploited the aspects that are negative, including slavery, condemnation of homosexuality and subjugation of women. Without knowing who wrote all this and why, it seems to me that they should be more open to the possibility that the Old Testament is the writings of some ancient people who may have been a lot like Joseph Smith and his elusive golden tablets, i.e charlatans.
