Aborigines The Worlds Oldest Inhabitants? The word "aboriginal" means "the first" or "earliest known". The word was first used in Italy and Greece to describe people who lived there, natives or old inhabitants, not newcomers, or invaders. Australia may well be the home of the worlds first people. Stone tools discovered in a quarry near Penrith, New South Wales, in 1971 show that humans lived in Australia at least twelve thousand years before they appeared in Europe. 26521kno41gsg8m So far three early sites have been discovered in Australia, the Penrith one being dated about forty-seven thousand years old, a Western Australian site forty thousand years old and another in Lake Mungo, New South Wales, thirty-five thousand years old. To put this in perspective, so that we can appreciate the time scales, since the first fleet arrived in 1788 there have only been 8 generations of settlers. On the other hand, there have been in excess of 18,500 generations of aboriginals!!!
