Why do egg whites happen?

It's not that egg whites "happen," but rather they are a part of an egg. Here's the breakdown:

* Eggs are made up of different components: The most noticeable are the yolk (yellow) and the white (albumen).

* Egg whites are primarily protein: Specifically, they are mostly water (around 90%) with protein called albumin as the main component.

* Albumin's role: It provides structure and protection to the yolk. It also plays a role in how the egg cooks.

* Why it's clear: The clear appearance comes from the high water content and the way the protein molecules are arranged.

So, it's not a matter of them "happening", but rather they are a natural part of the egg's structure and function.
