Where does scripture state that Eden was 'Heaven'?
Heaven is a paradise, is it not?
Did God create a Paradise?
Satan fell ONCE, not twice, and it was in the Garden of Eden, just prior to his tempting of Eve.
Jesus said Satan fell from heaven.
Ezekiel describes Lucifer (through his description of the King of Tyre) as falling from Eden, the Garden of God.
Isaiah describes Lucifer as wanting to "ascend into heaven," (which by this point in time is no longer Eden) something He can't do if he's already in the heavens (where's he gonna go?), and to "ascend above the heights of the clouds," something he can't do if he's already above them.
So here's your scripture that, as a whole, describes Eden as Heaven.
In the beginning God created the heavens and the earth.The earth was without form, and void; and darkness was on the face of the deep. And the Spirit of God was hovering over the face of the waters.Then God said, “Let there be light”; and there was light.And God saw the light, that it was good; and God divided the light from the darkness.God called the light Day, and the darkness He called Night. So the evening and the morning were the first day.Then God said, “Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.”Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; and it was so.And "
God called the firmament Heaven. So the evening and the morning were the second day. - Genesis 1:1-8

Then God saw
everything that He had made, and indeed it
was very good. So the evening and the morning were the sixth day. - Genesis 1:31

“How you are fallen from heaven, O Lucifer, son of the morning! How you are cut down to the ground, You who weakened the nations!For you have said in your heart: ‘I will ascend into heaven, I will exalt my throne above the stars of God; I will also sit on the mount of the congregation On the farthest sides of the north;I will ascend above the heights of the clouds, I will be like the Most High.’Yet you shall be brought down to Sheol, To the lowest depths of the Pit. - Isaiah 14:12-15

AND
“Son of man, say to the prince of Tyre, ‘Thus says the Lord God: “Because your heart is lifted up, And you say, ‘I am a god, I sit in the seat of gods, In the midst of the seas,’ Yet you are a man, and not a god, Though you set your heart as the heart of a god(Behold, you are wiser than Daniel! There is no secret that can be hidden from you!With your wisdom and your understanding You have gained riches for yourself, And gathered gold and silver into your treasuries;By your great wisdom in trade you have increased your riches, And your heart is lifted up because of your riches),”‘Therefore thus says the Lord God: “Because you have set your heart as the heart of a god,Behold, therefore, I will bring strangers against you, The most terrible of the nations; And they shall draw their swords against the beauty of your wisdom, And defile your splendor.They shall throw you down into the Pit, And you shall die the death of the slain In the midst of the seas.“Will you still say before him who slays you, ‘I am a god’? But you shall be a man, and not a god, In the hand of him who slays you.You shall die the death of the uncircumcised By the hand of aliens; For I have spoken,” says the Lord God.’ ”Moreover the word of the Lord came to me, saying,“Son of man, take up a lamentation for the king of Tyre, and say to him, ‘Thus says the Lord God: “You were the seal of perfection, Full of wisdom and perfect in beauty.You were in Eden, the garden of God; Every precious stone was your covering: The sardius, topaz, and diamond, Beryl, onyx, and jasper, Sapphire, turquoise, and emerald with gold. The workmanship of your timbrels and pipes Was prepared for you on the day you were created.“You were the anointed cherub who covers; I established you; You were on the holy mountain of God; You walked back and forth in the midst of fiery stones.You were perfect in your ways from the day you were created, Till iniquity was found in you.“By the abundance of your trading You became filled with violence within, And you sinned; Therefore I
cast you as a profane thing Out of the mountain of God; And I destroyed you, O covering cherub, From the midst of the fiery stones.“Your heart was lifted up because of your beauty; You corrupted your wisdom for the sake of your splendor; I cast you to the ground, I laid you before kings, That they might gaze at you.“You defiled your sanctuaries By the multitude of your iniquities, By the iniquity of your trading; Therefore I brought fire from your midst; It devoured you, And I turned you to ashes upon the earth In the sight of all who saw you.All who knew you among the peoples are astonished at you; You have become a horror, And shall be no more forever.”’ ” - Ezekiel 28:2-19

AND
And war broke out in heaven: Michael and his angels fought with the dragon; and the dragon and his angels fought,but they did not prevail, nor was a place found for them
in heaven any longer.So the great dragon was
cast out, that serpent of old, called the Devil and Satan, who deceives the whole world; he was cast
to the earth, and his angels were cast out with him. - Revelation 12:7-9

--------
NOTE: The "firmament called Heaven" is not talking about the sky or the atmosphere. It's talking about the firmament (Hebrew: raqia) that God created in the midst of the waters of Genesis 1:2. Contrast that with the "firmament of the heavens," which
is talking about the sky or atmosphere.
NOTE: Eden is described as having only one entrance. The only way this would be possible is if it were surrounded by a wall of impassable mountains. God cast Satan out of the "mountain of God."
NOTE: in the passage from Revelation, the devil was cast not "down to the earth," but simply "to the earth." This COULD be interpreted as him being cast out of the Garden to the earth.
