things humans do that aliens might not understand
- Laughter - Laughing is one of those things universally understood by all humans, regardless of their language or location. It’s a primal function. Other animals don’t tend to share this behavior, so it’s very unlikely that a being from another planet will.
- Crying - Excessive lacrimal secretions associated with distress have not been observed in any creature aside from humans. Like with laughter, this is a primal thing that humans are wired to understand and the odds are extremely unlikely that a species from a foreign planet will share this feature.
- Smell - Not every animal in the animal kingdom has a sense of smell. Dolphins, for example, can’t smell. Theoretically, another organism could be unable to smell in a similar way, and it could be an alien.
- Gender - Having an entire culture based around your genitals is pretty weird, when you think about it. It’s possible for aliens to have many different genders, or no genders at all. They may not even have the same number of sexes. Some animals have only one sex, and one member of the species is capable of reproducing with any other member of the species.
- Music - Humans like music because it falls within our acoustic and vocal range, and the tempo is similar to our heartbeat. Scientists have created “species-specific music” for animals, designed to be more fit for them. This has led me to believe that aliens could have a very different idea of what “music” is.
I wonder if anyone else on this website thinks about how aliens would interact with us, because this kind of stuff keeps me up at night.
