Eden is in the stretched out heavens which heavens were stretched out from earth on day 2 of creation week.
It is called "the breadth of the earth" which is not perceived by Job. It is the same bredth of the earth which the devil and his hordes ascend up to after the thousand year reign, to try to take over the City of God, there.
When Adam was created from the dust of the earth, he was "raptured/laqach" to Eden, and established in God's rest, there and placed there so as to reign over earth from there and have children and populate the earth. There would have been going up to Zion above and coming down if Adam had not fallen and got cast down to earth with no way back.
He ate of the fruit of the knowledge of good and evil and became defiled and died in spirit as a son of God and was cast down to the earth from which he was made.
Eden was the place the tower of Bab-el =gate of God- was being built to try to ascend to, by another way than the Way God ordained from the beginning.
Since the Tower of Babel rebellion, Eden above is veiled from the eyes of mortal man, who cannot find it for looking; just like the Sodomites looked all night but could not find the door into Lot's house.
Paradise is a name for Garden, and the Garden is Eden is Paradise, in the third heaven. The tree of Life is in the midst of it. Adam was raptured to there and lost his place and it is now veiled to the eyes of mortals.
The river was there and is there still, which became four heads.
Something I read recently is that Rivers "flow" in the atmosphere today -interesting.
2 Cor 12:12 2 I know a person in Christ who fourteen years ago was
caught up/raptured to the third heavenwhether in the body or out of the body I do not know; God knows. 3 And I know that such a personwhether in the body or out of the body I do not know; God knows 4
was caught up/raptured into Paradise and heard things that are not to be told, that no mortal is permitted to repeat.
Revelation 2:7
He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh
will I give to eat of the tree of life, which is in the midst of the paradise of God.
Gen 2:15
And the LORD God
took/laqach/raptured the man/Adam, and put him into the garden of Eden to dress/to

Genesis 2:9
Out
of the ground the LORD God made to grow every
tree that is pleasant to the sight and good for food,
the tree of life also in the midst of the garden, and the tree of the knowledge of good and evil.
2 Esdras 4:7
And he said to me, If I had asked you, How many dwellings are in the heart of the sea, or how many streams are at the source of the deep, or how many streams are above the firmament, or which are the exits of Hades, or which are the entrances of
paradise?
2 Esdras 6:2
and before the rumblings of thunder sounded, and before the flashes of lightning shone, and before the foundations of
paradise were laid,
2 Esdras 8:52
because it is for you that
paradise is opened, the tree of life is planted, the age to come is prepared, plenty is provided, a city is built, rest is appointed, goodness is established and wisdom perfected beforehand.
