“That relationship seems to have been one of God “walking” in the Garden with Adam and Eve.”
Most parents get along well with thier offspring s after they are married.
Please remember that I am not saying that Adam was “begotten” like Jesus.
Also, remember that we believe that we were spirit children before Father created the world for us. So yes, Adam left his parents in heaven to come to this life.
God directly describes making Adam out of the ground and placing him in the Garden of Eden. Then forming Eve for him. He says nothing about Adam being in heaven or leaving Him or any “mother.”
Adam has no mother. He was made directly by God from the dust of the ground.
