You’re joking, right? They didn’t live to 40 years old lol.
They were basically caveman equivalent in terms of advancement. They wouldn’t have 99.9% of what they have now if not for the British. Would they have even invented the wheel yet? Probably not, since they hadn’t in 60,000 years…….
Not a single person alive today would want to go back to living how the aboriginals did. If they did, they could just go and do it in the outback - nothings stopping them. They could go and have their average life expectancy of 30-35 years old, forage and hunt, and so on. Why don’t they?

You say worst tragedy, I say the start of our country as it is today. Wars happen, countries get colonized - accept it and move on.
Oh no, not the meaningless racism cry……
