FILL THE EARTH WITH HIS CREATED MAN.
The Lord God formed man in the beginning, male and female He created man after His own likeness. Unfortunately, this created man was lost ever before they were seen outside the Garden.
The garden in Eden was to help train Man and his wife for the greater works awaiting them outside the garden. But ever before they'd come to that understanding, the man was lost!
Adam slept with his wife and had many children from his fallen image. They gave birth to people but "hu-man" in figure, a reduction in creativity. This is lesser than the created man, appearing in the glory of man, which now is the fallen image of God.
The created man is the image of God, fashioned as male and female in God's likeness. God allowed the fall of Man during his trial because (1) Of devil's determination to steal, kill and destroy the created man (2) He wanted a level ground for everyone else coming into the world (3) God wants everyone saved simply by grace.
Excuse me, are you the image of God or image of human? Do you reason like God or more like a higher animal? Have you had your "second birth" after your parents put you to bed? Have you got the privilege to be born by God Himself? Have you been "born again" by the Spirit of the living God? Do you live in the Holy Ghost or by human reasoning? Does God's seed of eternal life abide in you? Or you belong to the Serpents??
Serpent beguiled man till they fell short of the image and glory of God. It told man that he was from the dust and thence, man was deceived, just so it could gain superiority over them. It led them into error, then corruption. It made man sought after wisdom than waiting for God, made them desire another "work" of their own and "children" of their womb - to eat from their own sweat....but didn't reveal the real reason behind his actions - it deceived them and Man fell.
God had blessed man saying, "Be fruitful and multiply, FILL THE EARTH..." but with kind of people? With the CREATED MAN – the man He created! God charged man to FILL THE EARTH with His own very nature, not ours; with the right people He made. Anyone who hasn't been made or re-created by God is unfit for propagation or everlasting production. They are just "not viable".
