The plain old Homo Sapiens, the sheep domesticators - see U1. This is what God said:
7 So Jehovah said: I am going to wipe men whom I have created off the surface of the ground, from man to domestic animal, to moving animal and to flying creature of the heavens, because I do regret that I have made them (Genesis 6).
Now God himself proceeded to make 'the man' in his image (Genesis 1:27). But as regards mankind he said: Let us make man in our image according to our likeness (Genesis 1:26). So 'man' was made by a plurality of heavenly beings whereas 'the man' was made by the singular God. It is manifestly apparent that Homo Sapiens was not made directly by God, because he had so many prototypes (Homo Erectus, Homo Habilis, Archaic Homo Sapiens, Neanderthal man etc). God would not have needed to make any prototypes, since he knew everything before he said let there be light.
It the involvement of the whole heavenly organisation, the 'earth' that mankind was 'out of' as Paul said:
47 The first man [is] out of the earth, [he is] a dusty [one]; the second man [is] out of heaven (1 Corinthians 15).
In the literal meaning the first man is Adam and the last is Jesus. But there is more because the first man is both out of the earth and made of dust. So by the Power Principle of the code, his being out of the earth has a greater meaning than being made of dust which we know already. By the Successive Articulations Principle of the code, this being 'out of the earth' is the key symbolism. The symbolic meaning is the first man, Homo Sapiens, pre-adamic man, was made by God's heavenly organisation and the second Adam was made by God himself.
Look! Homo Erectus, Homo Habilis, Archaic Homo Sapiens, Neanderthal man and finally Homo Sapiens or modern man were not various attempts by God to design mankind. They were the various design stages that the angels went through in producing us. God on the other hand just produced Adam out of dust in one shot. He does not need several prototypes to know what he is doing.
Now as we know from I5, the pre-adamics were unable to procreate via sexual reproduction so they would die out if the angels stopped giving them babies. Now Peter said...
19 In this [state] also he went his way and preached to the spirits in prison,
20 who had once been disobedient when the patience of God was waiting in Noah's days, while the ark was being constructed, in which a few [ones], that is, 8 souls, were carried safely through the water (1 Peter 3)
5 And he did not hold back from punishing an ancient world, but kept Noah, a preacher of righteousness, safe with 7 others when he brought a deluge upon a world of ungodly people (2 Peter 2).
7 So Noah went in, and his sons and his wife and his sons' wives with him, into the ark ahead of the waters of the deluge.
8 Of every clean beast and of every beast that is not clean and of the flying creatures and everything that moves on the ground,
9 they went in by twos to Noah inside the ark, male and female,
just as God had commanded Noah (Genesis 7).
So we must deduce that the total number of human souls in the ark was 8, Noah, his wife, his 3 sons and their wives. So no pre-adamics came through.
7 So Jehovah said: I am going to wipe men whom I have created off the surface of the ground, from man to domestic animal, to moving animal and to flying creature of the heavens, because I do regret that I have made them (Genesis 6).
The flood destroyed the sons of Adam and their offspring, not the pre-adamics who were raptured before it came. Presumably they were the servants of the adamics as the angels are of God. Eve was to become the mother of everyone living, so Adam knew the pre-adamic procreation would end. In fact we now understand that Adam was far more intelligent than pre-adamic man. Adam was made a little lower than the angels, by the divine engineering prowess of an omniscient divinity. Whereas the pre-adamics were several valiant angelic attempts to put the spirit of God into a fleshly being. These early ancestors of Adam were made a lot lower than the angels - see Intro5. Their cave paintings are the work standard of a modern day child - not of Michael Angelo.
7 You made him a little lower than angels; with glory and honour you crowned him, and appointed him over the works of your hands (Hebrews 2).
4 What is mortal-man [Enosh in Hebrew] that you keep him in mind, And the son of earthling-man [Adam in Hebrew] that you visit/go to him? [God visited Abraham in Genesis 18 - see U154]
5 You also proceeded to make him a little less than gods [angels], And with glory and splendour you then crowned him (Psalm 8).
20 After this Adam called his wife's name Eve, because she had to become the mother of everyone living (Genesis 3).
'Eve' actually means 'living [one]'. Eve could not become mother of everyone living until after Adam died of course. So the pre-adamics might have died out during Adam's 930 year life, or possibly they lasted until the flood.
