The creation story is given to us by God as the opening of His "Love Letter to Man" - that's the Bible... I do not think He intended to give us a science book. I do believe that He gave it to us so that we could understand the beginning of the human story and learn from it.
Gen 1:1 - 2:3 tell the story in a global manner...
Gen 2:4-24 tell the beginning of man's story
think of it this way... the first sets the stage, the second begins the drama, and what a drama it will be... the drama of the history of the people of Israel
