Which is my central point, whether law writings or prophesy - the Scriptures beginning in Genesis 2 - focus on the life (or not) of Adamic men.
Non-Adamic men are brought into the story, the promise, later through Jesus Christ (the Song of Moses is sung along with the Song of the Lamb in Revelation 15, sheepfolds, etc.)
Your distinction between “Adamic” men and “non-Adamic” men is unorthodox and extrabiblical. It is a distinction that the Bible does not make. The word neshamah is used in the Old Testament to refer to any member of the human species (including pagan civilizations such as the Hittites and Canaanites, Deut. 20:16-17) and expanded upon in the Flood account to include any other air-breathing creature. Any other interpretation is simply not in the text. The biblical account does not give any room for such flights of fancy.
