You do know that a straightforward reading and a literal reading of a passage that is written in a Hebrew style that is not poetic, yet Hebrew does have a poetic style. Must be a reason why they did not use it here.
Jesus did not reference the parable of the good Samaritan, He TOLD it, and everyone knows it was a story. It is such that in some translations of the Bible it says so. The stories Jesus told were parables, which means they had deeper spiritual meaning. If the story of Creation was not true and only a story, why was it the underpinning of Jewish society? if only a story... Their Ten Commandments include one that is based on Creation. Either God lied when He gave the Commandments, or He knows more than we do. In Martin Luther's time, they were defending against people who basically believe God snapped His fingers and it was. (Actually, it was more it only took God one day.) Martin Luther defended 7 days against this, because the Bible said 7 days.
Magical fruit? Perhaps it is better to have a literal understanding of Genesis. Then you don't see magical fruit, you see a command of God backed up by a piece of fruit which had no power in and of itself other than to, by implication of breaking the Law of God, opening the eyes to good and evil. The impact of the sin was instant. Everything was cursed because of sin. (Notice how God even cursed the earth and creation.) You say death existed before rebellion, yet death is suffering and pain. So how can there be death if there is no suffering? How could a perfect world (I don't think God could create anything less than perfection) be so imperfect?
God explained it to them. As for plants, even the Hebrew uses a different word in relation to life for plants and life for animals. Different words, because it is different. Plants were made to be food for all creation. It wasn't until after Noah's flood that animals became fully part of the food chain. (I do forget that a lot of people toss out most of Genesis.)
If Adam was not created by God, then Jesus death means nothing. If there was death, disease, and suffering before the fall, and Jesus came to redeem us (to make things as it was), how is death, disease, and suffering any better than death, disease and suffering? How is that eternal life? He is coming to restore things to the way they were before sin corrupted everything.
