Aboriginal heritage and culture, in terms of its historical continuity, is one of the oldest on the planet. Rock paintings at Olary in South Australia have been dated as 34.000 years old. Aboriginal people themselves believe that they have lived on this continent since the beginning of time.
After the discovery of Australia by Europeans, the number of Aboriginal people has decreased continuously and in 1994, there were 300.000 Aboriginal and Torres Strait Islander people in Australia.
There are many different tribes with different language. They have differences and similarities in their myths, life styles and cultures. The Anthropological surveys in the last five decades shows that there were 300-500 Aboriginal languages and ten percent of Aboriginal people still speak their indigenous language.
In Aboriginal Myths, there are many stories that tell relations between terrestrial beings and celestial beings. They are simply told but signify the celestial roots of human.
Myths invariable evoke a sense of awe because they are dealing with great and profound mysteries. The initiated Aborigines keep the secret meanings of their myths. There are some stages of initiation in Aboriginal societies. And in these initiations, secret meanings of myths and songs, rituals and ceremonies are passed to new initiate ones orally. Each song is a celebration of the unique role of a Spirit Ancestor within the sacred landscape, each song an integral part of Creation itself.
Dreamtime is an important concept to understand Aboriginal myths related with creation. Supernatural beings, which will until that time had slept beneath the surface of the earth, rose to create the world in the Dreamtime. The Arrente term altjiranga ngambakala has the inference of 'having originated out of one's own eternity', 'immortal', 'uncreated'. This is the essential concept of the Dreamtime or the Dreaming. At the same time, 'altjirarma' means 'to see or dream eternal things' or 'to see with eternal vision'. Before the earth came into existence, there was a mass of dark and formless matter, a vast watery expanse or a somewhat featureless plain. Spiritual Ancestors
