[Mark17]

If all that was required is we say, "sorry", and that's all that is needed, then Adam and Eve could have done that and we would still be living in the Garden of Eden eating strawberries. ;o)

Well, in the Garden of Eden, Adam and Eve, at least in the eyes of man, made just a small, rather innocuous little mistake, a small little bit of disobedience. It didn't matter much. It was no big thing. They only fell slightly off the cliff, but they were kind of still hanging on. They would recover.
In God's eyes, however, that one little, tiny, meaningless sin, was totally hideous to Him, and mankind fell completely off the cliff, all the way, infinitely past the bottom floor, with no hope of any kind of recovery whatsoever, for all eternity.
Whatever people may believe, or not believe about it, is irrelevant to God. He knows the truth, and has communicated that truth to us in the pages of both the Old and New Testaments. If people do not wish to accept that, then that's on them. They only thing they have to look forward to, is a certain fiery indignation, (lake of fire) the "wrath of God." Imagine that, the wrath of God, a concept so completely unfathomable, that no man can ever even begin to understand it. I have NO desire to experience that wrath, even though I deserve it. Make sense?

Well; they didn't INTEND to get into trouble; besides; at this point in time; what difference does it make?

Does it make sense? TOTALLY! It is a fearful thing to fall into the hands of the living God. (Heb. 10:31) Thankfully, we can be rescued from that fearsome fate because of His great love and grace.
