Who is The Real People from Mutant Message Down Under and what is their importance?

Marlo refers to the Australian Aborigines as "The Real People," suggesting this is what they in fact call themselves. Their society is, she claims, similar to indigenous societies around the globe (North American Indians, African nomads, etc) - in tune with nature, experiencing a strong spiritual connection to the spirit of life, living free of material and/or political attachments or agendas. The lives and philosophies of these societies, and of "The Real People" in particular are, she writes, simple but mystic, ancient but thoroughly in the moment, faithful and reverent within their own culture but deeply suspicious of outsiders and at times violently protective.
