Just curious. I really don't.
I think that's an interesting question.
First, we should read Genesis chapters 2-3 with a true listening, without trying to see this or that idea, but really to learn the deeper lessons.
Things like the essential deep issue for our souls like: Trusting in God, instead of ourselves, ultimately....
---------
But, once we do really listen, and really hear, and have these invaluable deep lessons, then we could just for fun ask the very much less important questions about what parts were
only literally concrete (none, some, much, all, etc....) and what parts instead of just-concrete (alone) have deeper meaning.
But, since the meanings are
crucial for us, let's look at one.
Here's a great example of something with a deeper meaning:
Genesis 2:22 And from the rib that the LORD God had taken from the man, He made a woman and brought her to him.
Of course God
could have chosen to form Eve from the ground, just like Adam....
From "dust" or from "mud".... Or from a piece of Adam's skin(?).... Or a thigh bone marrow?....
But He
didn't choose those.
Instead, He chose a part of Adam close to his heart.
She is for Adam closer than his own skin. She in some sense protects his very breath, and heart.
Those are the kind of messages we are to absorb from scriptures, see. They are
profound, and deeply helpful in life.

About the relatively unimportant speculation on concrete details. My total speculative guess is that the Garden was literally on the Earth -- not in another dimension, even though it has the wondrous, time-stopping (or time-altering)
Tree of Life (!!)....
But this is only speculation, and not really important if person A or B guesses correctly about some esoteric detail about 'when' or 'how' or such. (only the profound meanings really matter)
