It will end in this manner: if indeed you are "in adulthood", as you emphatically implied at my expense here, and yet you cannot discern the moral difference between removing a head of grain from its stalk, and removing the head of a living soul from its neck, then it is no wonder civilization has come full circle and is once again just as it was in the days of Noah.
Thus you have not only an issue with disbelief concerning the flood narrative, but also a more serious issue with believing the Testimony of the Master in the Gospel accounts: for he uses that phrase, "as in the days of Noah", (Mat 24:37-39, Luk 17:26-27), and therefore, logically speaking, he affirms the flood narrative as holy writ or he would not have used it, and moreover other authors of holy writ likewise believe and use it in various scripture discourses such as Isa 54:9, Eze 14:14-20, Heb 11:17, 1 Pet 3:20, and 2 Pet 2:5.
The scripture calls the land animals and the great sea creatures living souls. The scripture does not call herbs and fruits from fruit trees living souls. You didn't study it out, and therefore do not believe the scripture: thus your moral compass allows you to believe that removing a head of grain from its stalk is no different than removing the head of a living soul from its neck.
