I am trying to understand the reference(s) to natives, especially Tasmanian aborigines, with comments that they were isolated and could not have come in contact with those who had heard of God or gods. The “image of God” as part of the human race deals with spirituality and the capacity to contemplate matters pertaining to God or as human understanding degenerated, of gods and related concepts. Attempts to incorporate such matters with biological theories will fail.
The aborigines conveyed spirituality as the dreamtime which included creation myths and references to law. This from the internet:
The native Tasmanians shard a belief system with those of the mainland, but it was not well recorded before they were gone. What is known of their practices, their links and duties of care with named animals and places, in their taking the names of plants and animals, a belief in the transmigration of souls, in their dances of the various animals such as the emu, kangaroo, fire, wind etc. They show similarities indicating that they thought in similar ways to the mainlanders. They also had tracks that were followed by their Dreamtime ancestors as did the mainlanders.
The track followed by a Dreamtime creation being is a songline or a storyline, the track along which the ancestral being followed bringing everything into existence.
