So? Paul allegorises so surely that makes him a liberal, surely that means he doesn't really believe the Bible!
I don't know why it's so difficult to grasp that a piece of literature can be poetic in nature and still be describing actual historic events.
The Genesis account of creation is not giving us a literal scientific account, it is a prime example of an Ancient-Near-Eastern Suzerain-Vassal treaty, a covenant, with its introduction of a Great King, the prologue, blessings curses etc. It is clearly a document of its time, it is not a newspaper report, it is not an abstract from a scientific paper. This irrational fear of non-literal language (unless it has a 20 foot sign in neon above it screaming "THIS IS A PARABLE!!") simply betrays how engrained the post-enlightenment modernist way of reading a text is engrained in Christian thinking today. There is a kind of slavery to the thinking that only rationalistic scientific truth can be taken seriously and other forms are lesser so. Unless we try to understand the scriptures as it was intended to be understood by it's first hearers, then we are allowing our own cultural bias to influence our understanding rather than the original intent of the author.
I also suggest you look up Meredith Kline's Framework hypothesis, a work which truly seeks to put the creation account into its cultural context rather than forcing our own onto it.
And how anyone can say that Gen 1 is not like the poetry in the Psalms with its repetition and mirroring of words and phrases is baffling. Just because you don't like it doesn't make it so.
