In the beginning the earth was a bare plain. All was dark. There was no life, no death. The sun, the moon, and the stars slept beneath the earth. All the eternal ancestors slept there, too, until at last they woke themselves out of their own eternity and broke through to the surface.
When the eternal ancestors arose, in the Dreamtime, they wandered the earth, sometimes in animal form -- as kangaroos, or emus, or lizards --sometimes in human shape, sometimes part animal and human, sometimes as part human and plant.
