Romans 5 does not state we are condemned for Adam's sin; rather, that since Adam, all have sinned.
Romans 5:12-14 (WEB)
12 Therefore as sin entered into the world through one man, and death through sin; so death passed to all men, because all sinned. 13 For until the law, sin was in the world; but sin is not charged when there is no law. 14 Nevertheless death reigned from Adam until Moses, even over those whose sins weren’t like Adam’s disobedience, who is a foreshadowing of him who was to come.
Therefore, ever since Adam, people have sinned, and by their own sins they die.
Romans 5:12 Therefore as sin entered into the world through one man, and death through sin; so death passed to all men, because all sinned.
Why did death pass to all men?
Answer: Because all sinned.
No Scripture states that we die for Adam's sin.
Paul clearly states that sin was in the world before any law was given, but when God made a Law that was not obeyed, such as not eating of the Tree of Knowledge, then that sin was counted against them.
Romans 5:13 (WEB)
13 For until the law, sin was in the world; but sin is not charged when there is no law.
Therefore, ever since Adam (the first human to walk the earth), people have sinned, but that sin does not produce death until a Law is made showing us not to commit that sin.
Therefore the Law was given as our school master or tutor to show us our sins - we are then condemned by those sins because of the Law given - and then bring us to Christ Jesus.
Galatians 3:24 (WEB)
24 So that the law has become our tutor to bring us to Christ, that we might be justified by faith.
But before any Law of God was given, God did not count any sin against them.
Acts 17:30 (WEB) 30 The times of ignorance therefore God overlooked. But now he commands that all people everywhere should repent
But once the Law was given, Adam and all others after him, have broken God's Laws and are condemned for their own sins.

10 But glory, honor, and peace go to every man who does good, to the Jew first, and also to the Greek. 11 For there is no partiality with God.
12 For as many as have sinned without the law will also perish without the law.

Romans 7:7-8 (WEB)
7 What shall we say then? Is the law sin? May it never be! However, I wouldn’t have known sin, except through the law. For I wouldn’t have known coveting, unless the law had said, “You shall not covet.” [Exodus 20:17; Deuteronomy 5:21] 8 But sin, finding occasion through the commandment, produced in me all kinds of coveting. For apart from the law, sin is dead.
