It is vague story and more can be speculated than can be known. Their exact physical and spiritual status and existence is not well defined. Alive? Was their physical and spiritual existence changed the instant they eat the fruit....eating the fruit that is another issue, was it metaphoric. Or were they changed when they left Paradise? I am not suggesting either one conclusively.
Incorruptible blood? Not sure about that one. Were they incorruptible due to their innocence? Another discussion. The correlation between Adam and Yeshua is an interesting topic.
I take things literally, unless Scripture says otherwise. We can allegorize things for learning and instruction, such as the Red Sea parting, walking across on dry ground, and being clean escaped from our adversaries of sin, but it still happened physically as described.
I quoted the Scripture to show how one being alive without the law, and then when the commandment comes to condemn our transgression: which comes by God to our minds and hearts, then we die.
And so, they were alive, until they transgressed, and they were dead once God confronted them. They were no longer living souls, which is only by breath and Spirit of God.
They separated themselves from God by their transgression, no longer having the Spirit. (Is 59:2)(Jude 19)
They had uncorrupted blood by birth of God (Adam was the son of God), which they corrupted by sin. All life is in the blood, and so they had everlasting life in their uncorrupted blood, given by the Spirit breathed in them. That corrupted blood and sin nature and death passed on to all by flesh, except to Jesus, who came down from heaven born of a woman by the Spirit, with His own uncorrupted blood as He gave to Adam, to be the 2nd Adam.
Jesus chose not to transgress: He chose the Father in all things. His blood on earth remained uncorrupted to the end, and so now we have the
incorruptible blood of the Lamb of God available to all them that believe, with the eternal life of Christ therein:
Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you.
That is not symbology, but the truth when born of the Spirit and the seed of God: our inner man and new creature created after His likeness drink His blood, which is drink indeed, with life indeed therein.
His blood is now incorruptible, because there is no more trial for sin, because He did fulfill the law in death on the cross, so that His uncorrupted blood will remain so forever: it is was uncorrupted, and is now incorruptible.
That was the purpose of the commandment in the garden, to try Adam. And so are we also tried in the trial of our faith, not to transgress after the similitude of Adam, but to walk in the steps of the 2nd Adam, choosing to yield ourselves to God and Christ, not to obey the lust of the flesh, but to keep the faith of Jesus and obey His Word only to the end.
