Why do our bodies make methane?

Many people have wondered why our bodies make flatus, or gas (which is mostly methane). And many have wished that our bodies would stop doing it. However, flatus is an unavoidable product of helpful bacteria in the intestines. These bacteria live on the food we eat and help us digest our food. Flatus is a natural waste product of their work. When someone passes gas, that person is just getting rid of that bacteria waste product.
