Ah, It was Adam's transgression that "alienated us". That is more like it. Just to be clear, what was that all about that you might explain it that would explain why Paul would use the word "enemy" as in enemy of God? Could it be that Paul used "enemy" to explain "lost friendship"?
For if, by having our friendship broken, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.

The scripture bears out that we were these:
Romans 5:6 For when we were yet without strength, in due time Christ died for
the ungodly.
Romans 5:7 For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die.
Romans 5:8 But God commendeth his love toward us, in that, while we were yet
sinners, Christ died for us.
Romans 5:9 Much more then, being now justified by his blood, we shall be saved from wrath through him.
Romans 5:10 For if, when
we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.
We weren't friends of God or those who blessed the seed of Abraham. We are of those enemies that cursed God and Israel (Genesis 12:3 KJV).
Ephesians 2:11 Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands;
Ephesians 2:12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
BUT NOW!
Ephesians 2:13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
It is only through the apostle Paul that we see that the man Christ Jesus gave Himself a ransom for all (including the likes of us), to be testified in due time (1 Timothy 2:4-6 KJV)!
