First the sun was created by the BIG BANG...
Then there was another belt of asteroids created...
Soon they asteroids started moving towards the sun...
Due to the suns gravity...
After that a part of the sun broke up and went and stop about 8 light years away...
Then the big fiery ball cooled down and at last could sustain life...
This happened about 10 billion years ago...
