Put into perspective PZ547
The North American Amerindian would put 'feathers' in his attire and say he is "One with the 'Sky' Spirit" and that's as close to it as he got, besides turning his brain into a rotted cabbage with some help from Peyote.
While the White American lads flew over him in a thing called an 'Aeroplane (Jet, Shuttle, etc)' and gave the 'wannabe' below the 'bird'.
That's why 'they' lost North America.
...so when the Aboriginies were amazingly LAND (& Fire) orientated, their isolationism was also due to their lack of understanding WATER and thus they were both trapped (by water) and underdeveloped beyond 'just' Fire.
They chose the wrong element, you could say.
...OZ is probably the world leader in 'Water' technology.
