Germ Theory

The theory that infectious diseases are caused by microorganisms (or germs)
Real World Example
Imagine dealing with a messy room where clutter just seems to appear out of nowhere, making it hard to keep things tidy. Just like how small, unnoticed items like papers and trinkets can accumulate and create chaos, tiny microorganisms, invisible to the naked eye, can invade our bodies and cause infectious diseases. In both cases, the small, unseen elements—be it germs or clutter—are the root cause of the problem, leading to bigger issues like illness or a disorganized space if not managed properly.
