What you're suggesting is that Adam was the "anointed cherub that covereth", which is about a NON-FLESH ANGELIC being. Last time I looked at God forming Adam in His Garden of Eden (on earth) is that He made Adam flesh. Do I really need to show you that Genesis 2 Scripture about that?
The anointed cherub that covered is not the language of the Hebrew, and at least one English Bible translation tells it like it is...the angel covered...not Adam, not Satan...
Cherubim are mighty powerful and holy angels, and not one has fallen. Only some of the Watcher angels have fallen, and can never enter heaven again. Satan is still there, and has authority over earth since the fall of Adam, who sold the kingdom he was set over into the control of the Satan and his evil angels, who are still not cast down, but will be, for the last millennial Day of this present creation -until the grand finale at the end, before the Beginning, which is that 8th Day, and the New Beginning.
At any rate, Satan is not a fallen Cherub, was never a cherub, is not a fallen angel, and is an evil spirit created to do what he does, which is to try, test, and prove the watcher angels and the Adam creation. He is the accuser, and the Lake of Fire was made for him and his evil angels who are under him. Satan is not everywhere at once, as YHWH is, and has a host, an army, under his control to do what they do, which is to accuse those they Tempt who believe their lies and therefore disqualify themselves for the eternal Glory And fellowship with the One True God.
Satan could not test Job without permission from God to whom he answers. Satan got permission to try/test Peter, Jesus said, and Jesus said He had prayed for Peter and to strengthen his brethren after he got the victory, so to speak.
As to where Paradise is, always has been, and always will be, you need to check the Word of God on that.
2 Cor 12: It is [a]doubtless not profitable for me to boast. I will come to visions and revelations of the Lord: 2 I know a man in Christ who fourteen years ago—whether in the body I do not know, or whether out of the body I do not know, God knows—
such a one was caught up to the third heaven.
3 And I know such a man—whether in the body or out of the body I do not know, God knows—
4 how he was caught up into Paradise
Revelation 2:7 “He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes I will give to eat from
the tree of life, which is in the midst of the Paradise of God.” ’
