Decoding Fear: The dark

Everyone fears something. We all know that. Have you ever wondered why? I hope to use my imaginary degree in philosophy to discuss these fears. The first one I choose to philosophize about is the dark.
Why are we so afraid of the dark? It is simply the absence of light. Right? But for some reason it feels so much more sinister. As kids it made us hide under our covers and call out to mom and dad. The vague shadow we could see became goblins or demons or some other type of monster. We would try to avoid it with night lights, but the darkness would always come.
I believe all of fearsomeness of the darkness can be explained easily. When it is dark you cannot see. It sounds simple but think about it. Your brain is a complicated piece of equipment. Its job is to interpret data and extrapolate facts. The lack of light means there is no data for your brain to take in. That lack of things to do allows your brain to just make things up. Think about it even as an adult you will still experience weird things when you look deeply at the darkness. That feeling that someone is behind you, the sound of foot steps, or maybe you can swear you saw someone walking through the dark. Things like this make the darkness eerie. Your brain makes the unknown strange and the strange frightening.
Or maybe there is something supernatural about the dark. Before the beginning, before God made light, there was one thing, darkness. It represents the chaos before the order that became the universe. On the other hand it could be the embodiment of the chaos inside of every human being sitting there waiting for the right moment to take over. Maybe that is why we are so afraid of the darkness that comes with each night. I guess the world shall never know.
