So no one was created on the 6th Day? Just the concept of a single male and female? Perhaps you should not know the name Lilith either. It has effected your grammar.
There is a real glaring proof that there was only Adam and Eve created, and no other people, the fall in Eden into sin when those two, Adam and Eve followed the devil and disobeyed God's command.
If there were millions or even just one more person alive, it would not have been righteous of God as the great judge to force the innocent other people out of the garden, who knew no sin and were not disobedient, setting their bodies to perish and them losing their lives also in His judgement because of what 2 people did. IF a person did not eat of the fruit, then they did not know good and evil.
And Adam was alone, there were no other people created until God made Eve for him.
Genesis 2
16 And the Lord God commanded the man, saying, “Of every tree of the garden you may freely eat; 17
but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die.”
18 And the Lord God said, “
It is not good that man should be alone; I will make him a helper comparable to him.”
Genesis 3
22 Then the Lord God said, “Behold, the man has become like one of Us, to know good and evil. And now, lest he put out his hand and take also of the tree of life, and eat, and live forever”— 23 therefore the Lord God sent him out of the garden of Eden to till the ground from which he was taken. 24 So He drove out the man; and He placed cherubim at the east of the garden of Eden, and a flaming sword which turned every way, to guard the way to the tree of life.
Romans 5
Death in Adam, Life in Christ
12 Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned— 13 (For until the law sin was in the world, but sin is not imputed when there is no law. 14 Nevertheless death reigned from Adam to Moses, even over those who had not sinned according to the likeness of the transgression of Adam, who is a type of Him who was to come. 15 But the free gift
is not like the offense. For if by the one man’s offense many died, much more the grace of God and the gift by the grace of the one Man, Jesus Christ, abounded to many. 16 And the gift
is not like
that which came through the one who sinned. For the judgment
which came from one
offense resulted in condemnation, but the free gift
which came from many offenses
resulted in justification. 17 For if by the one man’s offense death reigned through the one, much more those who receive abundance of grace and of the gift of righteousness will reign in life through the One, Jesus Christ.)
18 Therefore, as through one man’s offense
judgment came to all men, resulting in condemnation, even so through one Man’s righteous act
the free gift came to all men, resulting in justification of life. 19 For as by one man’s disobedience many were made sinners, so also by one Man’s obedience many will be made righteous.
20 Moreover the law entered that the offense might abound. But where sin abounded, grace abounded much more, 21 so that as sin reigned in death, even so grace might reign through righteousness to eternal life through Jesus Christ our Lord.
