ELI5 why flies and other bugs love to land on people and fly around their heads?

You would think they would learn to fly far away while my hand is trying to smack them.

They don’t have the cognizance/brains to understand the connection between flying around you, your hand, and its connection to you. Aka they’re too dumb to know you’re trying to swat them, they’re just trying to avoid a giant hand. Also they probably think you smell nice. Nice is subjective. Wasps like meat, flies like poo or any sort of strong smell like food. If you smell like those things, you might attract them. Bees and butterflies like nice smells like perfumes and fruit and flowers, so you might attract them if you smell nice. Bugs don’t know they’re being annoying, they’re just being bugs.
