亞當、夏娃墮落前：

(1)。蛇是罪的化身，是否可以說亞當、夏娃墮落前罪已在世界上存在了？

三木森答案：NO。聖經中罪的定義是遠離神。在亞當夏娃墮落前，雖然撒旦犯罪，但是在靈界。儘管神允許撒旦進入蛇體內(為了試驗人) ，但撒旦還不能對我們的這個世界起作用。因為蛇為動物，沒有自由意志，不會犯罪。羅馬書明說，罪是由一人進入世界的。所以，始祖墮落前，我們的世界沒有罪。

You did not take the entire biblical revelation into consideration. You also unduly restricted the meaning of world to mean the earthly world, without first clarifying as such in the question. The word world in the bible can mean more that this. Sin, pre-existing due to angelic rebellion against God before the creation of mankind, entered (by Satan) into our earthly world from the world above (the heavenly realm or heavenS), part of the larger world we live in.

(2) 亞當、夏娃吃園中的果子，是否說死亡已在世界上存在了(果子被吃了，死了)？

三木森答案：NO。聖經中說的死亡，是由罪引起的，受上帝的咒詛而會自然死亡，不能永生。或生物界的自相殘殺。意思是“死做了王” 。在始祖墮落前，地里的出產，是神命定供人享用的，不會自然死亡，除非人享用了它們，只是一個設計的代謝循環的環節。只有當始祖墮落後，大地(或大自然) 也受到咒詛，地才不為人效力了，才長出荊棘等，自然界才有了自然的死亡，凋零。也才有了互相殘殺。“死才做了王” ，沒有永生了。

Without declaring your presumption about the genesis creation models, you already assumed that there was no biological death of any sort before Adam's fall. Death in the bible has two-fold meanings: physical and spiritual. Can physical death be designed, a priori, into the present cosmos due to fall (spiritual death) of mankind posteriori? Nothing really stops the Creator from doing so. You actually admit this concept in the following answer.

(3)。如果亞當、夏娃不墮落，人類不斷繁衍，是否會把世界擠滿了？

三木森答案：NO。上帝預見到了人類會墮落，才有目前的世界。如果人不墮落，上帝也會預見到，那麼世界可能就是另一個。並且，神說要生養眾多，布滿大地。那麼布滿大地後，或許生育就停止了。反正，他有辦法。

Good, you admit that God created this type of world based on his foreknowledge of the fall of man. The physics of this cosmos would be very different, had man chosen to obey God. The new heaven and new earth is one such a wonder world.
