There's a guy in Australia who made some "history" book called the "Dark Emu’ that pushes the idea that Aboriginal Australians were not just hunter gatherers and that they had settlements , agriculture, aquaculture and food storage. His own self proclaimed motivation for writing this fake history is to "rebut the colonial myths that have worked to justify dispossession"
Just to give you an idea of how ridiculous this claim is that the Aboriginals had these type of advanced settlements. The Australian government once had to release a PSA video telling the Aboriginals not to sleep on the road or they might get run over by cars. Does this sound like the kind of people that would have had agriculture, aquaculture and food storage?
As you can expect though, this book got a lot of awards and gets promoted in libraries and schools
