    The Maori people of New Zealand believe that the world began in darkness.

    They say it was dark because Rangi, the sky father, and Papa, the earth mother, were lying together, keeping out of the light.

    Rangi and Papa had many children who were all gods (神). Their children did not like the darkness, so one of them, Tane, the god of the forests, made his mother leave his father. After that, the sky stayed far above the Earth, and let the light in.

    Later, Tane was living on the Earth. He wanted to have a wife. There was no woman around, so he made one from sand. He breathed (呼出) life into her, and she became the first human(人类).
