Why do we smile?

Smiling is a display of happiness, and people who do not smile appear unhappy. Smiling makes one look inviting or approachable, so it’s especially useful when interacting with strangers. A smile can also be used to hide true feelings, which might make the person being lied to feel more comfortable if they think everything is fine instead of worrying about what the truth actually is.

Smiling is also a response to positive stimuli, or something that makes you happy. It's just something that you feel. It’s not just that you are in an enjoyable situation, but also that your brain feels pleasure and signals for your body to display the happiness by smiling.

There are many other factors that affect why we smile, but those are the main reasons I was able to come up with.
