If you read “The Science of God” and other books by the author Gerald L. Schroeder, he posits that Adam was when man gained a soul.
What makes us human is not our thumb, our self-awareness (you can easily embarrass a cat), but what we know we are not. We long for immortality, for purpose and meaning. Our soul is where this resides, IMHO.
We are created in the image of God, and God is triune - Body,Spirit,Soul.
To say God is not “good” because somehow there are lifeforms similar in statue that may / may not have had a soul is to set one’s self up to judge God, a dangerous role. And who is to limit God to say that these are not the “other sheep” spoken of? If you believe in classical Christianity, it is only Jesus who, by a person’s relationship with, salvation comes. Romans 1 says that no man has an excuse, because even if no missionaries made it to the “hobbit’s” island, God himself would give each soul what he required, if he only would embrace the truth. Romans 1 answers a lot of questions about the so called “hermit in a cave that never heard” about God.
Cool. So then I have nothing to worry about.
