Im not sure if this is the right board for this but its something i have always wondered about.
What would have happened if in 1770 Captain Cook arrived in Australia to find the aboriginal people have formed a advanced society (equivalent of early 21st century technology). The Aboriginals had mastered all the technology which we all take for granted today (trains, electricity, cars, HD tv's, roads, internet, satellites, planes and weapons which Cook could have only dreamed of etc) but for whatever reason they had no interest in exploring the rest of the world.
This thread is assuming that instead of forming nomadic tribes 45,000 years ago the Aboriginal people slowly improved their society with inventions and social reforms at a faster rate than what was happening in Europe.
What would have happened when Cook returned to England and word spread around Europe of this extremely advanced race of black people on the other side of the world?
