Who says reason for world war III will be Petrol?
Reason lies in two words "Me and Mine".
There are a lot of bacteria in there, many of which produce different gases and breakdown the leftover food in different ways.
I often tell my students that we are each unique ecosystems for the things that live on us and in us, producing unique mixtures of symbionts, and one gross example of that is how we all smell different.
There are a number of gases that contribute to the smell, but methane is not one of them. Methane does not have any smell, that is the reason why they mix it with mercaptane, a sulphur containing gas before sending it to your stove: so gas leaks can be detected
Now, the gases that do smell. First of all H2S, which indeed smells like rotten eggs. Then there a number of those before mentioned gases-mercapatens- but different from the one they use in stoves(that is why it doesn't smell like feces). then there are some amines, mainly cadaverine and putresceine, produced by the intestinal flora. And many more...
