Sounds like you and I were on the same road, you took a left turn and I took a right turn.
What I discovered is that what Genesis calls a DAY is NOT talking about a 24 hour day. I also found that there is nothing in the Bible that indicates this earth is a young planet. Rather the exact opposite. So one has to watch who does the translating.
That's what I always figured.
It was a whole raft of things that made me change my mind. But it was the realization of the mindset of many Christians on this issue that really drove me away. It would take much more time than I have today to explain.
