Yes I can and I have repeatedly. None so blind...
Paul isn't talking about Cain, Adam is named as well as Christ.
For since by man [came] death, by man [came] also the resurrection of the dead.For as in Adam all die, even so in Christ shall all be made alive. (! Cor. 15:21, 22)
This is what happens when you habitually take the clear meaning of Scripture and distort the meaning.
Bear in mind that our Lords patience means salvation, just as our dear brother Paul also wrote you with the wisdom that God gave him. He writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort, as they do the other Scriptures, to their own destruction. (2 Peter 3:15, 16)
Type yes, figure no.
The word actually means:
From G5180; a die (as struck), that is, (by implication) a stamp or scar; by analogy a shape, that is, a statue, (figuratively) style or resemblance; specifically a sampler (type), that is, a model (for imitation) or instance (for warning) (Strong's Exhaustive Concordance)
This is how the word is used in other passages:
tupoi
1 Cor 10:6, here it means literal idolaters are examples of what not to do.
1 Cor 10:11, here it means literal people who murmured, same meaning.
1 Pe 5:3, here it means literal leaders of the church are examples not Lords.
tupon

tupouV

Paul also makes mention of Adam in his first letter to the Corinthians. There is no indication that Paul is speaking figuratively of Adam:
For as in Adam all die, so in Christ all will be made alive. (1 Corinthians 15:22)
So it is written: "The first man Adam became a living being"; the last Adam, a life-giving spirit. (1 Corinthians 15:45)
What he is saying is that the literal and historical Adam was a 'type' of Christ. Typology is not a figure of speech and you know this.
No, let's assume nothing, lets' understand the clear message as it was originally intended to mean and stop distorting the Scriptures. Paul is describing literal history, there is no indication otherwise and you know it.
The Scriptures offer an explanation for man's fallen nature, how we inherited it exactly is not important but when Adam and Eve sinned we did not fast. This is affirmed in the New Testament in no uncertain terms by Luke in his genealogy, in Paul's exposition of the Gospel in Romans and even Jesus called the marriage of Adam and Eve 'the beginning'.
Because the King James Bible translates tupos (G5179 τύπος

as 'figure' you pretend it means that Adam is a figure of speech.
You actually try to argue that Paul is speaking of Adam figuratively Paul makes this statement regarding Adam:
Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression, who is the figure of him that was to come. (Romans 5:14)
Yes it is clear but you can keep chanting your mantra of 'Adam is figurative' and no one will correct you, no one except me and 2,000 years of Christian scholarship.
That's not a mistake, it's an evident and obvious fact. You have been shown enough times what a sound exposition of the text looks like and you insist and denying the clear testimony of Scripture. As many times as you do it I will show you what Paul means by what his words actually mean.
This is how you are trying to generate credibility for theistic evolution? By twisting the clear meaning of words to fit your philosophy of natural history? I think you have been betrayed by a world view that is based on assumptions that fold like a house of cards under close examination. The fact that you have the audacity to keep making an argument that has already been refuted tells me that you don't have a legitimate one.
Have a nice day
