ELI5: If you make a chicken soup lets say, and then boil it every night for like 10 minutes (or however long it takes to kill all the bacteria) could you keep it in your fridge indefinitely without it going bad??

No. Unlike what the other poster said, though, it's not because of bacteria between boilings or (usually) toxins produced by them. Bacteria between boilings would simply be killed with the next round and with most bacteria we encounter, it's an infection of the live bacteria in our bodies, not the toxins they produce, that cause illness. 

The problem is that your refrigerator isn't a sterile environment. Bacteria simply don't grow as quickly in there because it's cold. You might as well put the soup outside on a cold winter day. There are bacteria floating everywhere in the air and on every surface in your fridge. These will contaminate the soup. 

If you could sterilize the soup and put it into a sterile container and store it under a nitrogen atmosphere it would remain sterile. This is how most packaged foods with a long expiration date are preserved.
