I feel like any aliens that were prey at some point in evolution would have an odd fear of humans. Mostly cause they look like predators, act a bit like predators, and ARE predators. One perfect example is when we're focused on something like a mosquito that's been bugging us for a long time and we are just done.
Human: "Found you." *absolutely desimates the mosquito, squashing it into a million pieces as it's guts and various body parts liquidize into blood of the bloodthirsty, now stained on the palm of the human. A living being now reduced to a useless corpse as the human wipes the remains on their pants*
A reminder: if you were taught that mosquitoes in general are useless to the environment and could be eliminated “without consequence”, then you were taught incorrectly. People still regularly comment this silly notion on my posts with absolute confidence. Our goal is reducing risk to humans, NOT eliminating the dangerous animal altogether.
You don’t have to like irritating, gross, or dangerous animals (most people do not), but if you are ever arguing for the extinction of an entire animal species try to remember the natural world is unfathomably complex in ways none of us can predict.
