I think fear of the dark is a remnant of an old human instinct from as far back as the beginning of human sentience. To a cat or an owl, there is nothing to fear of the dark because they can see in darkness. Darkness is their realm. But us humans have very poor night vision, so the darkness is not our realm, and therefore 'The Unknown'. And, like any animal with good sense, it's often considered better to avoid the unknown and remain safe, than to probe the unknown and risk injury/death.that was so educational. I am glad. You used that. For science, you monster
But since we are humans and have the ability to rise above our animal instincts, probing the unknown is something we do on a regular basis. It's called science. :)
