Are there any apocalypse myths other than Ragnarok in which some people survive to repopulate the world?
In the story of Ragnarok, Lif and Lifthrasir survive by hiding in Yggdrasil, and presumably they go on to repopulate the world after all the fighting is over.
Are there any other cultures whose end-of-the-world myths explicitly include some survivors who could potentially rebuild civilization?
This question is partially intended as an experiment to figure out what qualifies as "too broad", as prompted by this meta question. Like the question discussed there, this one's "target area" includes potentially every culture on the planet, but I believe this one has a slightly more specific criterion.
Would Christianity count? In one eschatological tradition, true Christians are raptured, then return to (a new) Earth with Jesus Christ. They don't exactly repopulate though; they re-inhabit.
Another possibility - if Christianity counts - would be Noah; would flood myths be appropriate?
@El'endiaStarman I was under the impression the Biblical "New Jerusalem" (or whatever it was called) was more like an eternal afterlife rather than someone surviving on the existing Earth. But I could be wrong.
...ACTUALLY...I just realized that the eschatological tradition presented in the Left Behind books has a few people *not* raptured that survive through the 7-year Tribulation and get to live in the New Earth/New Jerusalem. They don't reproduce after the 1000-year reign, however.
I provided an answer to help with the experiment. Even if the question is "too broad" I think that it is answerable with a couple examples. I provided the typical "Gods send flood. Only chosen survive", but there may be other examples different than floods that depict the "a handful of chosen rebuild civilization" myth.
Yes. Many different cultures and mythologies depict really similar stories about floods. There are only a handful survivors of the flooding, who have to repopulate the earth.
For the Sumerian version of the myth, Enlil sends a flood to kills the too-numerous and too-noisy humans. The god Enki intervenes and warns the king to save his family and a collection of animals. Babylonians have a similar version of the myth in which a man called Tnapishtim built a boat, took aboard his family and a selection of craftspeople and animals. The well-known Judeo-Christian version of the myth has Noah build an ark, take aboard seven family members and representatives of all land animals to survive a global flood. The list goes on.
