Just curious. I really don't.
I do believe that they were literal people because of 5 reasons.
1) Genesis 1 - 3 was written as literal history.
There are many genres in the Bible. The Bible is not just 1 book, but 66 books under 1 binding. With each book, there are different genres, many times in 1 book. What is a genre? A genre is a category of artistic composition, as in music or literature, characterized by similarities in form, style, or subject matter. The Bible is full of them: History, Poetry, Prophecy, Parables, and so forth.
Most Biblical scholars agree that Genesis is written in a narrative sense, such as the literal 6 creation and a literal Adam and Eve. Now, a lot of the scholars do not believe in a literal creation, but they agree that Genesis 1 - 11 was written in a narrative (or in a historical) sense.
And also, very interestingly if we say that Adam and Eve are figurative than literal, then we can assume that his descendants were not literal as well. Noah might as well not existed, even though Jesus said that he did exist, and so did a few more places in the Bible. Noah couldn't exist unless Adam existed because Noah was in Adam's generation line and no being can be a descendant from a myth.
2) Adam's activities require a physical body.
In order for the first acts of sin to have been taken place, there has to be a physical being to commit the sin. In Genesis 3, it says that Eve was tempted, before she and Adam ate the fruit that God commanded them not to eat of. They had a choice to obey God to not to obey God. When they choose to disobey, they brought in sin and death into this world. So the question is this: Did death bring man into the world or did man bring death into the world?
Romans 8:21 - 22 said:
Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God. For we know that the whole creation groaneth and travaileth in pain together until now.
Romans 5:12 said:
Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
So it is clear in scripture that there has to be a physical action that has to have taken place. In Romans 5, it is clear that it is referring that Adam was a literal person. If the one man did not bring sin into the world and ultimately death by his actions, then Romans 5 would not make any sense.
3) Adam is the first man in Christ's unbroken genealogy.
Remember what I said about Noah cannot be a descendant from a myth? The same thing applies to Jesus Himself. Multiple places in the New Testament gives that Jesus is in the lineage of Adam. Luke 3, for example traces back all the way back to Adam. Matthew 1 traces back to Abraham, which you can trace that back to Adam both in Genesis 5 and 11 and also in Luke 3.
4) The rest of the Bible references Adam as a literal person.
Jesus mentions about Adam a few times, so did Paul, and several others. Jesus said in Matthew 10:6: "But from the beginning of the creation God made them male and female." He was referring to Adam and Eve as being literal people and that God made them and then joined them together as a symbol of marriage.
Job also believed that Adam was a literal person. In Job 31:33, it says "If I covered my transgressions as Adam, by hiding mine iniquity in my bosom." Job has to be referencing an historical person in order to say that, not a mythical or a figurative person.
Paul even references Eve being from Adam's side. "For Adam was first formed, then Eve." (1 Timothy 2:13). "For we are members of his body, of his flesh, and of his bones. For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. This is a great mystery: but I speak concerning Christ and the church." (Ephesians 5:30 - 32).
5) The Gospel depends on a literal Adam.
If Adam isn't real, then the Gospel doesn't make any sense. Jesus came to be our savior. Save us from what? It is from sin. But what is sin without Adam rejecting God? It is clear in Romans 5 that death reigned from Adam and by Adam's disobedience, sin entered into the world and then death passed unto all men. If that wasn't true, then the reason about why Jesus came would come into question.
And I think there is 1 more reason to add unto this. If Adam and Eve are not real, then how do we know the rest is real then? We should believe either the whole Bible or none of it.
Anyways, I hope this helps.
