Comment on 'Australian Aborigines 'world's first astronomers': study'

According to this article, tens of millennia ago, Australian Aborigines as far back as 10,000 to 20,000 years ago had started the navigation of the sky and implemented a time-keeping system marked out by seasons. Even their fishing and harvesting timetables had originated from the movement of the stars (i.e., Seven Sisters star cluster). Research has shown that the sky's changes were recorded through ancient songs and ceremonies that depicted heavenly events like an eclipse binging a Sun Woman and Moon Man making love. In my opinion, this is proof that man was intelligent from the beginning when life events where mapped out just by looking at the stars for a time table of life.
