Why do you say that the ancestors of Australians were criminals?

Australia's aborigines, mainly indigenous blacks from Africa, came to Australia 60 thousand years ago. Until modern westerners found them, they were still in the era of hunting and gathering, and the number was very small.

After James Cook, an Englishman, discovered Australia, the British government decided to use Australia as a place of exile. 17 17, the navy commander Arthur Phillips led 700 criminals to Australia, landed in New South Wales, and formally established a British colony.

In the early colonial period, the production and construction in this area were mainly carried out by criminals. Criminals exiled to Britain in the early days built a series of infrastructure in this area and developed local forests. In the following decades, hundreds of thousands of criminals were transported to Australia to engage in production activities. The production activities of these criminals played an important role in the early development of Australia and also had a certain impact on the formation of Australia. So it is usually said that Australia was founded by criminals.
