Gen 3:8 And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God amongst the trees of the garden.
The cool of the day is in the evening when the sun is setting. Location is the Earth.
The sun sets on Mount Eden in the third heaven, also.
It is a realm of the outstretched heavens that Adam was taken to and where he would rule earth from, as the first, "firstborn human being son of God". He lost the glory, lost the position of firstborn son of God of the human being kind, and by that, is dead in spirit, and cannot bear sons of God to "plant the heavens" and "build up the heavenly Zion's glory" as the temple not made with hands for the Glory to indwell, by having "living to God" sons . We lost it all in the fall.
Malachi 3:15 states He made the male and female one, having a remnant of the spirit, because He sought godly seed, which means "sons of God".
Adam was "son of God" -Luke 3:38, but not since the fall, and we are dead in Adam and must be born again, adopted into the One New Man living Spirit, which is Christ to be part of the restored kingdom of God and "plant the heavens", which is the purpose He created us for, to be living stones in His Temple not made with hands [human being sons filled with the Glory of God]....
.
Because Jesus paid the ransom price by His blood for our soul to be made clean, and adopts us into His One Living Spirit, then we have a Father who is "firstborn son of God of the human being kind", and the kingdom is going to be fully restored and God's plan for this creation will go forth in the New Man name.
There is a throne on Mount Zion of the third heaven that is prepared for the Son of Man to rule over the kingdom from, and Adam lost the opportunity to reach his destiny in his fall, but the New Man has bought every seed of Adam back [whosoever will], by His Kinsman/Redeemer blood of Atonement, and has ransomed the earth and will take His authority and sit on that throne as Firstborn, and will be our own "everlasting Father" by the adoption and He promises to share His ransomed throne with us, and we will reign with Him, forever, from where our first father, the Adam, would have, if he had not sold us into slavery to corruption and death.
The Adam was taken to the Garden/Paradise of God, and at the fall, was literally cast down, positionally, from the third heaven, to the earth below.
Before that, he could come and go, for they were united, but the Cherubim with flaming swords barred the way.
Nimrod & CO later tried to climb up by another way than the closed entry door/gate, and built a tower with the plan of taking over up there, but after building for 40 years, his tower was destroyed, his city destroyed that he was building, and the 70 tribes one mother tongue (proto Hebrew) was confounded/mixed up, into the 70 tongues -which have grown like branches on a tree into over 6,000 from the Hebrew mother tongue.
After the fall of the tower, Noah's sons' tribes began to scatter over the earth, divided by tongues, as the land mass was also being divided into the different continents from the one land mass of creation week, and their years of their lives were "cut short", so as to make it harder, by shorter lives, to be united against God's plan for salvation for the lost Adam race...
...Gen 3:14 And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
God has animals in the Garden also, but the entire curse is not a snake losing legs, but Satan received the authority to curse by corruption all flesh of all creation on earth, and Death and Corruption feed Sheol, in the belly of the earth, and Destruction is one of the Satan's who is the king of Sheol/Hell, in the belly of the earth. In Greek, He is called Apollyon, but in Hebrew, He is Abbadon, king of the belly of the earth, where Sheol is.
There is a kingdom of darkness that Adam sold his kingdom to, by his disobedience to God. The Prince of Darkness got legal authority over all flesh, to curse it.
The Hebrew of that passage is clear.
The promise of the Seed/Christ was made in the same passage, and He who was to come in flesh to undo the curse by ransoming the kingdom back for Himself to rule and reign over, by His once for all Atonement, and who is "Seed" of the Woman [Jerusalem above is that Woman, spiritually] has come, and has ransomed back the kingdom, but He has not yet taken His power unto Himself and reigned. He does that at the beginning of the Millennial Sabbath reign.
So the curse was pronounced by God over all flesh, and the Creator gave Satan the authority to "eat the flesh/dust" of all creatures, and to hold souls captive in Sheol below, until the time appointed.
He took , to heaven, all the righteous and innocent souls [the souls of those who die before coming to understand good and evil and choosing to do evil]
from that death of separation from the Father,
out of that prison house at His resurrection,
and to heaven,
to wait with Him there for the resurrection and regeneration of their human flesh bodies.
The rest of the souls held captive by Death in Sheol will be resurrected to their final judgment at the end of the millennial reign, when Sheol and Death will be cast into the Lake of Fire and no more will the belly of the earth hold captive souls.
