Of course all people are condemned to death, but it's because of Adam's sin and the consequences that come from that, not from some unknown mystery time before the world began. Man was created on the earth and became a living soul at the time God breathed into him the breath of life.
While agree with the gist of your post, I have to point out that people are not condemned because of Adam's sin but because of their own. This is not only a clear principle in the Old Testament but it is a major aspect of the gospel that many people miss.
Romans 15:12 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.
Ezekiel 18:1 The word of the Lord came to me again, saying, 2 “What do you mean when you use this proverb concerning the land of Israel, saying:
‘The fathers have eaten sour grapes,
And the children’s teeth are set on edge’?
3 “As I live,” says the Lord God, “you shall no longer use this proverb in Israel.
4 “Behold, all souls are Mine;
The soul of the father
As well as the soul of the son is Mine;
The soul who sins shall die.
5 But if a man is just
And does what is lawful and right;
6 If he has not eaten on the mountains,
Nor lifted up his eyes to the idols of the house of Israel,
Nor defiled his neighbor’s wife,
Nor approached a woman during her impurity;
7 If he has not oppressed anyone,
But has restored to the debtor his pledge;
Has robbed no one by violence,
But has given his bread to the hungry
And covered the naked with clothing;
8 If he has not exacted usury
Nor taken any increase,
But has withdrawn his hand from iniquity
And executed true judgment between man and man;
9 If he has walked in My statutes
And kept My judgments faithfully—
He is just;
He shall surely live!”
Says the Lord God.
The entire chapter of Ezekiel 18 goes on like that, repeating the same point in various ways. God does not punish people because of the sins committed by their ancestors.
