I too have been all over the outback, and I find your skepticism unwarranted. If you’d had any time with the culture, you’d understand how important it is for us to value their stories, rather than push imperialism at them.

That you are unsatisfied is of no relevance to the fact that the studies are solid. The evidence is in the stories and the geological record. I hope there is much, much more research done on this subject in the near future, for some to criticize and others to truly value an incredibly important culture, on the brink of extinction, precisely because of the types of Euro-centric, imperialist views you proffer being applied to their existence.

"rather than push imperialism at them."

Dude, all I am saying is that I have not read any claims by any researchers that there is absolute proof of any sort. You have such a claim, then just show it.

And imperialism has nothing to do with whether the oral history of the aborigines goes back 40 000 or 10 000 or just 1000 years. British imperialism succeded, because they had superior weapons.
