I spent more than 30 years in the Christian church. The bible was always presupposed to be the word of God. At some point it became impossible for met to continue to work under that presupposition, and I lost my faith.
I believe there are real theological problems with accepting a molecules-to-man version of evolution. Anotomical humans have been around for 200,000 years, while recognized human behavior in our species is 50,000 years old. The God of the OT (if you discount the first 11 chapters of Genesis as "pre-story" revealed himself to Abraham about 4000 years ago. So God basically ignored humans for well over 90% of the time we've been around. If sin is such a bad thing that we need to be saved from (the whole basis of the Christian faith) then God sure took his sweet time doing something about it. It leaves me less than convinced that the bible is conveying truth.
