Certainly, there are many ways that people interpret it just as you viewed your interpretation below:
however,
Gen 2:16 And the Lord God commanded the man, saying, Of every tree of the garden thou mayest freely eat:17 But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.
is still written and the word "die" in the original is plural (spirit, soul and body)
and Gen 3: Thou shalt not eat of it: cursed is the ground for thy sake; - is very specific and our bodies is made up of the ground.
So, at the least I have some basis for my position. And there is absolutely no scripture to say they were going to die physically so to say they were not going to live forever in their bodies is an interpretation.
17 But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.
It says they would die if they ate the fruit, but it does not say that otherwise they would live forever. To say had they not eaten the fruit they would have lived forever in their bodies is an assumption. It is an even bigger assumption to say that all of humanity would have lived forever if Adam and Eve had lived forever.
Here is one explanation of the story from a Baha’i perspective, which is allegorical:
“Therefore, this story of Adam and Eve who ate from the tree, and their expulsion from Paradise, must be thought of simply as a symbol. It contains divine mysteries and universal meanings, and it is capable of marvelous explanations. Only those who are initiated into mysteries, and those who are near the Court of the All-Powerful, are aware of these secrets. Hence these verses of the Bible have numerous meanings.
We will explain one of them, and we will say: Adam signifies the heavenly spirit of Adam, and Eve His human soul. For in some passages in the Holy Books where women are mentioned, they represent the soul of man. The tree of good and evil signifies the human world; for the spiritual and divine world is purely good and absolutely luminous, but in the human world light and darkness, good and evil, exist as opposite conditions.
The meaning of the serpent is attachment to the human world. This attachment of the spirit to the human world led the soul and spirit of Adam from the world of freedom to the world of bondage and caused Him to turn from the Kingdom of Unity to the human world. When the soul and spirit of Adam entered the human world, He came out from the paradise of freedom and fell into the world of bondage. From the height of purity and absolute goodness, He entered into the world of good and evil.
The tree of life is the highest degree of the world of existence: the position of the Word of God, and the supreme Manifestation. Therefore, that position has been preserved; and, at the appearance of the most noble supreme Manifestation, it became apparent and clear. For the position of Adam, with regard to the appearance and manifestation of the divine perfections, was in the embryonic condition; the position of Christ was the condition of maturity and the age of reason; and the rising of the Greatest Luminary
4 was the condition of the perfection of the essence and of the qualities. This is why in the supreme Paradise the tree of life is the expression for the center of absolutely pure sanctity—that is to say, of the divine supreme Manifestation. From the days of Adam until the days of Christ, They spoke little of eternal life and the heavenly universal perfections. This tree of life was the position of the Reality of Christ; through His manifestation it was planted and adorned with everlasting fruits.
Now consider how far this meaning conforms to the reality. For the spirit and the soul of Adam, when they were attached to the human world, passed from the world of freedom into the world of bondage, and His descendants continued in bondage. This attachment of the soul and spirit to the human world, which is sin, was inherited by the descendants of Adam, and is the serpent which is always in the midst of, and at enmity with, the spirits and the descendants of Adam. That enmity continues and endures. For attachment to the world has become the cause of the bondage of spirits, and this bondage is identical with sin, which has been transmitted from Adam to His posterity. It is because of this attachment that men have been deprived of essential spirituality and exalted position.”

30: ADAM AND EVE
Whereas, the body of Jesus is an eternal body as the Second Adam and thus it is natural to believe the First Adam had the same type of body until he sinned.
I do not know what scriptures you are basing that upon, to say that the body of Jesus is an eternal body. I believe that Jesus has an eternal body, but it is a spiritual body, not a physical body.
This excerpt from the longer passage above describes the Fall of Adam..........
“For the spirit and the soul of Adam, when they were attached to the human world, passed from the world of freedom into the world of bondage, and His descendants continued in bondage. This attachment of the soul and spirit to the human world, which is sin……”
This is congruent with what Jesus said about being attached to this human world, that we would lose eternal life thereby.
John 12:24-26 Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit. He that loveth his life shall lose it; and he that hateth his life in this world shall keep it unto life eternal. If any man serve me, let him follow me; and where I am, there shall also my servant be: if any man serve me, him will my Father honour.
I have no problem with this additional understanding. There is both a spiritual truth as well as a natural truth because what we see is always manifested by what we cannot see:
NLT By faith we understand that the entire universe was formed at God’s command, that what we now see did not come from anything that can be seen.
So, just like "God said" and it was created, likewise the Word of God which bestows eternal life and is the highest degree of the world of existence, it is manifested with a physical body that is eternal.
Your view is the spiritual part and mine is the manifestation of the spiritual realm that created an eternal body much the same as Jesus' body.
I do not know why you need a physical body to be eternal. I believe that we will all have a body like Jesus’ body, a body that is eternal, but it will be a spiritual body, not a physical body.
“The world beyond is as different from this world as this world is different from that of the child while still in the womb of its mother. When the soul attaineth the Presence of God, it will assume the form that best befitteth its immortality and is worthy of its celestial habitation.” Gleanings From the Writings of Bahá’u’lláh, p. 157
“The answer to the third question is this, that in the other world the human reality doth not assume a physical form, rather doth it take on a heavenly form, made up of elements of that heavenly realm.” Selections From the Writings of ‘Abdu’l-Bahá, p. 194
That we will be raised in a spiritual body is congruent with 1 Corinthians 15, and it is clearly explained in this article:
Won’t the Dead Rise Again?
What Paul said is congruent with what Baha’is believe.
Baha’is believe that souls go to heaven and take on a spiritual body, which is the same thing as what Paul says in 1st Cor:
We are raised in a spiritual body because only spiritual bodies can enter heaven.
1st Corinthians 15
35 But some man will say, How are the dead raised up? and with what body do they come?
36 Thou fool, that which thou sowest is not quickened, except it die:
42 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption:
43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:
44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
46 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
53 For this corruptible must put on incorruption, and this mortal must put on immortality.
The verse above says nothing about the physical body being
changed into a glorified body that cannot die. The verses above clearly state that there are two kinds of bodies, a natural body and a spiritual body; we are sown in a natural body and we are raised in a spiritual body.
There is no way for us to understand what that body will be like, or what the spiritual world will be like, because there is no frame of reference for the spiritual realm of existence (heaven), since it is so different from this realm, nothing like we have ever seen or experienced. In the same way, we ourselves might find it impossible to describe to a child in the womb of its mother the reality of this world. We could talk about trees and birds and swing sets, but the words would evoke no meaningful mental images, and nothing useful would have been imparted.
