Basically, I think what you’re saying is that every human created after Adam and Eve was not created by God,they were created by Adam who has replaced God’s power to create due to sin?
This heretical idea would mean that God did not will anyone else after Adam and Eve,thus making Adam the creator of every human soul after original sin.
Do you believe this,or do you believe that God willed us?
God is the One Who can create anything - man simply discovers. God created creatures and plants to pro-create themselves, after their own kind, as God had established.
To say that humans are not created in the image of God is NOT the same as saying God does not have a will regarding the birth or life of man. But Scripture says God created Adam and Eve in His image, and Scripture says all offspring are created in the image of their Earthly parents.
