The Aboriginal believed that the world was made by the spirits(their ancestors) in the Dreamtime.
Everythings was made by they.
Thought anothers Aboriginals believed that they and everything was made by a Snake.
The story about How the Sun was Made begin when there not be humans on the Earth yet.
Dinewan the Emu and Brolga, they were fighting.
Then when Brolga angered she took a egg from the nest of Dinewan and threw it up to the sky.
Then the egg broken up at a heap of firewood and burst, and lit up the world and the creatures astonishment by its bringhtness.
A good spirit looked that and ever since he and their attendants collect wood for keep the fire, and send out the Sun to lit the world.
The next part I don't understand very well.
It told about that that many sleepers ( I think that these was also spirits) not awoken and they want some noise to awake them.
Then they one day heared a loughter of Goo-goor-gaga and after they agreed that he must use his laugh to awake them.
I like the way on that all cultures has myths to describe the world creation though many of them are similar and that part also is interesting.
I readed another story about the Sun, in this told about a Rainbow Snake but I don't know which are the more known because I readed about the Rainbow Snake in a website in Spanish.
