>There will be no shitskins
There won't be any skins. Everyone will be dead.
>Direct descendants of winter chan
You can't repopulate a planet with only the descendants of one person
>The world will be repopulated by two human survivors
You can't repopulate a species with only two people. Plus how would they be the children of winter-chan if they're human survivors as in people who were alive before the world ended
If the gods intend to kill everyone and start anew, they would also have to consider people who have already prepared to survive the end times. This includes everything from governments and militaries with state of the art bunkers to survival nuts.
Also killing off everything is just going to kill off any chances of the humans surviving because every other living thing will die too. Turns out very few species can actually survive in a frozen hell hole. The world won't be able to replenish itself fast enough.
This whole thing is retarded.
