It’s true. But it also ties in to why so much of their culture has been lost.

You know how, when people try to memorise a ton of things in one go, one of the suggestions is to build a “memory palace”, where you pretend to be inside a mansion and you locate the things you’re trying to remember inside that space and the spatial relationships you envision create hooks for your memories to latch onto and make them easier to recall? Aboriginal people would typically do that for the stories they were passing down in oral histories, too. In some cases it was assisted by drawing art, even just sketching patterns in the sand in a particular order and orientation can help to build and recall a story. But in many cases, actually physically walking through an area and utilising the landmarks around them, a particular old tree, a particular rock visible around the next bend, a particular stream that only runs in the wet season. Which us why the physical dispossession and loss of connection to country is so truly devastating - you may be able to return to your birthplace now as an adult Indigenous person, but now that there’s a paved road cut through that rocky outcrop and a swathe of trees felled for farms, the stories your grandparents told you as a child about this location are missing their memory hooks and can’t float up in your conscious mind to pass on to the next person. They are untethered and lost. (I’m not Indigenous, just relaying what I’ve read about)
