I believe a creator God brought this universe and all its components - living and otherwise - into existence and set its processes in motion. How he did it is for science to try and explain, and I see no conflict between science and the Bible - which is more concerned with WHY God created the universe, than HOW.
It's a shame that some posters, apparently vehement atheists, feel they need to boost their positions by attacking and belittling anyone who disagrees with them.
And it's a shame that Christians keep trying to engage in a fruitless debate instead of living their lives the way Christ wants them to live. Arguing never brought anyone into the Kingdom of God, and shaping America into a religious nation is definitely not what Jesus was talking about when he talked about the Kingdom of God.
