Why does faeces smell so bad?

Sudden this came to my mind : why does faeces smell so bad? And I asked God .

So "God" said "The bacteria inside of the feces is what makes them smell so bad. Specifically, the bacteria produce various compounds and gases that lead to the infamous smell of feces. Just in case you were wondering, you can get very sick by eating feces because it contains so many types of bacteria and other harmful substances such as parasites. So we wouldn't suggest adding feces to your diet any time soon. "

And faeces is : mostly made of water (about 75%). The rest is made of dead bacteria that helped us digest our food, living bacteria, protein, undigested food residue (known as fiber), waste material from food, cellular linings, fats, salts, and substances released from the intestines (such as mucus) and the liver. Although feces are made up of about 75% water, this number varies from person to person, depending on how long the feces stay in the intestine. Since the intestines absorb water from the feces, diarrhea (poop that passes quickly through the intestines) will contain more water and retained feces (which stay in the intestines for a longer amount of time) will contain less. Another point worth mentioning is that fiber helps feces pass along the intestine.

There you go.

Oh.. so sleepy.. don't want to type anymore.
