In Gen 5, Adam is not a singular male individual (a common misconception) — Adam is a group of people:
5:1 This is the book of the generations of Adam. In the day that God created man, in the likeness of God made he him;
2 Male and female created he them; and blessed them, and called their name Adam, in the day when they were created.
3 And Adam lived an hundred and thirty years, and begat a son in his own likeness, after his image; and called his name Seth:
4 And the days of Adam after he had begotten Seth were eight hundred years: and he begat sons and daughters:
5 And all the days that Adam lived were nine hundred and thirty years: and he died.
Adam “begat a son in his own likeness, after his image” (5:3) — that means that Seth is not a singular male individual. If you will spend some time with the majority of names in Genesis, etymologically (way back), you will fined they can be (and were) read in a “plural” sense — I choose the plural because it opens a way of explanation that is logical.
Back in those days, it was kinda like the hills of Missouri. The topography had a lot of “hollars” or small valleys where one group would have an offshoot or family go over the hill to another small (or larger) valley until they grew out ot it, and so on. They were spoken of or referred to as the “leader” of the group. E.g., the “house of David” was spoken of as David.
I know you are going to have a difficult time with what I am saying, however, I will continue to explain if you choose.
ICor 15:45 And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
46 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
47 The first man is of the earth, earthy: the second man is the Lord from heaven.
We who believe are the body of Christ. The term “man” is mankind or a group. Adam = Mankind. In the Bible there is a difference between the words “man” and “male” and “woman” and “female”.
Here is the kicker — “Eve” (Chavvah) means and is equal to “life” or “living” — the first woman, wife of Adam. Eve is the “life” of Adam who is mankind.
