Collision Course, or the spinoff, The Ice Age Adventures of Buck Wild?

Yeah, some of the stuff that has been able to be confirmed via geological studies is just insane. It's crazy to me how they aren't more widely known for disrupting the idea of prehistory.

If I had money I'd spend all my time learning from these people

Well, cultures that heavily relied on oral traditions developed systems that prevented a telephone type scenario from happening. Aboriginals combine oral traditions with ceremony, song, dance, and different medias of physical art. They also had respected leaders whose whole position was telling the right stories during specific times, at specific places, and to specific people in the tribe.

Aboriginal cultures have very advanced psychological technology which they use for the preservation of knowledge and the organisation of society. To white people, technology just means machines. But under a more holistic view, technology can be an idea that you use as a tool to do work. And Aboriginal cultures have very advanced mental tools. These tools have preserved knowledge for much longer than any book or clay tablet ever has, thanks to the expertise in psychology which was used to invent them.

Karl Marx referred to the economic organisation of cultures in Turtle Island and Australia as "primitive communism." But there's nothing primitive about it. Ask Me about Aboriginal farming.

Wiped out by Christinaity, for the most part.

While the aboriginals underwent and still endure settler colonialism it hasn't been as long or quite as thorough as the Roman occupation and then christianization that the celts went through. Australia is also so much bigger than the UK, so it would be hard to complete a very effective act of genocide against spiritual or tribal leaders as they did to the druids.

Even so some Celtic oral traditions were still going on strong up till the 19th century, often being little changed over thousands of years.

Well... The Romanisation of Europe happened.
