All is forgiven :)
We all make mistakes in interpreting other people’s words, and where there is no body language to help interpret, it’s harder. I’ve done it myself.
There is one thing about the Genesis account. If sinless Man did not fall, why did mankind need a Savior at all?
And one other thing. I do believe the Genesis account, but one must admit that it is light on the details. For instance, how long were Adam and Eve in the Garden before their expulsion?
If a long time, were they having marital relations? If not at long time, why didn’t they have children before the expulsion?
Did God offer them a chance of Redemption, or are they like the angels who fell?
The answers to none of these questions is essential to salvation; but are, I think, interesting.
Many of the answers to your questions are found in Jewish Tradition. Of course, the chrstian concept of “salvation” is alien to the Hebrew Bible, so it causes a lot of problems.
