The story: god sends creatures filled with hunger to eat every living thing. Creatures attack couple, man closes door on wife so he can save himself. Creatures eat everything else. One creature eats all other creatures. Man builds a ghost machine to make spirit of woman become flesh again. It works. Turns out spirit woman made a deal with the last creature to make an endless supply of things to eat: her husband. Out of revenge for closing the door on her.

The opinion: In all of humanity's time on Earth we've never developed such a tech, and now an idiot, in a wooden shack would get the know how, and the components to make this technology?

Also, how would the last person in the world, with no supermarkets around become so fat?
