ELI5: Explain Like I'm 5

Atomic coherence

Atomic coherence is like a game where you have a bunch of tiny balls that are the same size and are the same color. All of the balls can be arranged in different patterns, but all of them must stay together in the same way. To keep the balls in their pattern, you need to keep them close together, making sure they are all in the same place. This way, all the balls stay together in one, coherent pattern.
