OldLadyKnowsNothing, it depends what you mean by "believe the Bible".
Jesus told many parables using metaphors, so it's not surprising that the rest of the Bible contains these. If I said "it's raining cats and dogs", you would know what I meant, and you'd also know I wasn't purposely misleading you, but trying to tell the story in a memorable way.
IMHO, the Creation story is very similar to evolution, in the order of events, but with a metaphorical timescale of "days". Science eventually gave us more details of how this happened.
As for Lot and his daughters... just because something is in the Bible, doesn't mean it's recommended. Isn't it just as likely that God wants us to learn from people's mistakes? And if we were supposed to copy the behaviour of those in the Old Testament, why would Jesus need to have come along and shown us a more loving way of life?
Some Christians think it's fine to take tiny little bits of the Bible out of context as the literal word of God, without looking at the message of the whole. Others prefer to see the Bible as a collection of books which together give an overview of humanity and our relationship with God, from the start of the world to its end. These were written by human beings doing their best to describe the God they had come to know, and the laws and behaviour of various people at the time.
I'm not a fundamentalist, so it doesn't worry me too much if not every Christian belives exactly the same as me. Hopefully what we have in common outweighs this. Christians are human beings so we're bound to disagree among ourselves sometimes. (Scientists disagree too, don't they?)
