According to the Bible, god already tried a reset by emptying the world of life with a massive flood. Just a few generations after, things were already going so poorly that god decided to introduce new languages so as to create divisions and prevent people from working together to achieve amazing things.
Now, we're supposed to believe that god needs to bring massive global destruction because humanity is divided and always in conflict? It sounds as if the previous plans were complete failures. Why would anyone think the next plan would be any better?
