Summary: This is a Hawaiian creation story about how out of the different types of darkness that existed at the time. From these three types of darkness came the creatures of the land, creatures of the sea, and creatures of the sky.
I think the darkness in the story symbolizes the disconnect between night and day and the different types of animals and creatures that represent the different types of darkness, and move towards the birth of the world.
I believe the darkness in the story represents the inevitable creation of humanity, as well as equality between the races of animals and humans. With the creation of light, there is more to the world than there was before.
I believe this story really represents the how the animals are an integral part of the Hawaiian society. I believe it also shows how animals were there before humans. It also tells that the creation of mankind was the birth of day, and before that was only night.
