It wasn't destroyed by a flood the first time. It also was not, nor will be, destroyed by a volcano.
So far Chup's answer seems best, but I guess this all depends on how you define "world" and according to other posts, what movie you have most recently seen. Oh, and, just because the "Earth" is destroyed doesn't mean the human race would end. At least not billions of years from now. Who knows what humans could accomplish in that amount of time. Or, maybe we'll just kill ourselves. Me, I hope to live forever, and I don't mean by some religious or spiritual means. I guess the same methods that could conceivably radically extent our life expectancy could also kill us. Image every living thing on Earth being consumed by nanobots or a virus transmitted cancer.
