Dreamtime (or The Dreaming or Tjukurrpa or Jukurrpa) stories tell of the great spirits and totems during creation, in animal and human form that moulded the barren and featureless earth. The Rainbow Serpent came from beneath the ground and created huge ridges, mountains, and gorges as it pushed upward. The Rainbow Serpent is understood to be of immense proportions and inhabits deep permanent waterholes and is in control of life's most precious resource, water. In some cultures, the Rainbow Serpent is considered to be the ultimate creator of everything in the universe.
