I have been looking at the whole argument between you guys about 'Creation V Evolution' and its pretty heated!
I became a Christian 27 years ago. My experience of God and what Jesus has done for me is real. I have seen God at work and have seen an amazing healing of my own mother of a chronic illness. It completely baffled my aunt (my mother's sister) who is a doctor how this happened and had no explanation for it.
That aside, Christianity IS about relationship to God through Jesus Christ and you know when you either talking to a brick wall or not!
I have done a theology course and biblical interpretation was covered; the first chapter in Genesis to cut to the chase is a poem. A poem that relates to the Sabbath. Its a not a scientific document or anything like that, but the reality is that God did 'create out of nothing' (the big bang theory verifies that), most scientists now believe there was a first Homo sapiens. Whether he or she was called 'Adam' or 'Eve' noone will know. The flood was real enough, the last Ice age caused world wide (but obviously not total coverage of a 300 foot rise in sea levels. The flood story originated from Babylonian mythology and excavations there around the city of Ur revealed flood sediment 1 metre thick ABOVE the old city. Massive flooding events due to melt water easily explains this.
Its not about believing in Science instead of God, but working it together. As Albert Einstein remarked:
"science without religion is lame, religion without science is blind."
