The "short explanation" is that the reference is to the Lord Jesus Christ on the one hand and satan on the other. No need to presume "the writer used the term in the corporate/collective sense!" in order to force the text to indicate something never intended by the Author.
and to clarify ... I am not a "proud, man-exalting, Adam-worshiping FWer". I am a born again believer in the Lord Jesus Christ. I follow Him ... which is something you would know if you were not so interested in removing those who are members of His body (1 Cor 12:21).
God explains quite concisely in Gal 3:16 ...
Galatians 3:16 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
This does not negate the fact that believers are joint-heirs with Christ ... which is a great and precious promise in and of itself. However, the Lord Jesus Christ is the Heir spoken of in Gen 15, Gen 17, and the promise to Him is culminated in Rev when the Lord Jesus Christ returns as King of kings and Lord of lords.
I've told you more than a few times ... Luke 3:38.
The Lord Jesus Christ is the only begotten of the Father (John 1:14).
The genealogy in Luke traces the lineage of Jesus through Mary ... and goes all the way back to Adam, the son of God.
Yes ... there is a "third option!"
The offering made by God was sufficient to atone for the sin of Adam ... the coat provided to Adam was sufficient to cover his shame.
nope ... I have provided the third option.
Is it your claim that Eve remained in Eden?
Eve did not birth the Messiah. Adam fathered Seth. Seth is named in the genealogy of the Lord Jesus Christ ... at the end of the day, both Adam and Eve were vessels of honor.
not universal salvation, as salvation is by grace through faith.
What is revealed in the record is God's provision for remission of sin ... without shedding of blood is no remission ... which God made known the very same day Eve and Adam sinned.

What comes first in the post-Fall narrative: God's decree to the serpent re Eve or Eve's faith?
Moreover, since you believe that God's atoning provision was alone EFFICACIOUS, then how come Christ's atoning provision on the Cross isn't efficacious, especially since God's atoning provision in the Garden also PRECEDES any evidence of faith in either Adam or Eve. Therefore, whether you care to admit it or not, you actually do believe that God's provision in the Garden was 100% efficacious! How convenient. You just change or ignore inconvenient scriptures when it suits you.
Finally, you deny or ignore the fact that there are indeed TWO corporate bodies of people in this world: Those in Adam and those in Christ. This is a universal truth! And since Adam was the seed of the serpent then all of Adam's spiritual progeny are also the devil's offspring (Jn 8).
And LK 3:38 makes perfectly good sense since Adam was not procreated, therefore, he could not proceed from anyone except from the One who directly created him.
