I agree with most of what you said except "primitive ideas". While I agree there is a lot of BS in the bible due to misconceptions, early world views (patriarchal, not scientific, etc), I still think that there are many advanced thoughts and ideas, for example what I make of jesus' words. I think he was spot on, on so many things that are still completely valid today (e.g. "You see the sliver in your friend's eye, but you don't see the timber in your own eye. When you take the timber out of your own eye, then you will see well enough to remove the sliver from your friend's eye", thats an absolutely evolved and fantastic quote imo)

So all I mean is, while I agree we cant take the bible as an accurate historical description, and recognizing the catholic church's mistakes, as well as the issues of edited bible,  i still think a reasonable person could open that book up and take good messages from it, as with most religious texts.  Its been years since I did read the bible or other such texts but some parts stuck with me and I def dont think it was lost time, it helped me see even better how similar a lot of aspects of main religions are, how they seem to arise from similar experiences of non-ordinary states of consciousness and certain revelations about existence that appear to be pretty persistent across the epochs and places
