The telling of a story begins with a narrative technique that sets the time and place for events to occur in the story world. In this case it is the creation event, the beginning of everything. It also sets the tone or mood for the rest of the story, in this case the mystery and wonder of God. As the preamble, it is brief; it is not intended to do any more than paint a backstory for the main narrative.And just why do I have to see it that way?
