The first humans to arrive in Australia are believed to have done so around 50,000 years ago, although the exact date is difficult to determine and is the subject of ongoing research and debate among archaeologists and other scholars.
There is evidence that suggests that humans may have arrived in Australia as early as 70,000 years ago, based on the discovery of human artifacts and fossils in various parts of the country. However, the majority of evidence points to a date of around 50,000 years ago, which is supported by radiocarbon dating of artifacts and other methods.
The first humans to arrive in Australia were likely part of a wave of migration out of Africa that occurred around 70,000 years ago, when early humans began to spread out and colonize new areas of the world. It is thought that they may have traveled to Australia by boat or on foot, using land bridges that may have existed at the time due to lower sea levels.
The indigenous peoples of Australia, known as the Aboriginal and Torres Strait Islander peoples, are the descendants of these early settlers. They have a rich and diverse culture that has survived for thousands of years and has contributed significantly to the development and history of Australia.
It is estimated that there were around 750,000 Aboriginal and Torres Strait Islander peoples living in Australia at the time of European settlement in the late 18th century. Today, there are around 700,000 Indigenous Australians, representing around 3% of the total population of the country.
