You are both correct; and I respectfully disagree that the “trees” are not “literal planta.” Certainly not NORMAL plants, but plants nonethelesss.
The plants:
Gensis 2.9: Now the LORD God had planted a garden in the east, in Eden . . . In the middle of the garden were the tree of life and the tree of the knowledge of good and evil.
The location, somewhere around Syria/Iraq, et al:
10 A river watering the garden flowed from Eden; from there it was separated into four headwaters. 11 The name of the first is the Pishon; it winds through the entire land of Havilah, where there is gold. 12 (The gold of that land is good; aromatic resin [e] and onyx are also there.) 13 The name of the second river is the Gihon; it winds through the entire land of Cush. [f] 14 The name of the third river is the Tigris; it runs along the east side of Asshur. And the fourth river is the Euphrates.
Forbidding of the first tree:
15 The LORD God took the man and put him in the Garden of Eden to work it and take care of it. 16 And the LORD God commanded the man, “You are free to eat from any tree in the garden; 17 but you must not eat from the tree of the knowledge of good and evil, for when you eat of it you will surely die.”
Forbidding the second tree:
22 And the LORD God said, “The man has now become like one of us, knowing good and evil. He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever.”
The guard:
23 So the LORD God banished him from the Garden of Eden to work the ground from which he had been taken. 24 After he drove the man out, he placed on the east side [e] of the Garden of Eden cherubim and a flaming sword flashing back and forth to guard the way to the tree of life.
Now I see...instead of unclean it is forbidden.
These are not literal trees though. Christ is the Tree of Life while you know who is the other tree.
