If you were to choose, would you choose dark or light?
Ya cain't have a light without you gotta dark to stick it in.
I choose light because darkness is the absence of light (at least in the visible spectrum). In astronomical terms, light is usually derived from a star of sorts; darkness on the other hand could potentially involve a lot of things, a black hole being an example but most probably it is just a vacuum in space.
I'm not sure true dark even exists. The entire universe is filled with Cosmic Microwave Radiation which IS just a wavelength of light (Radio/Microwave). There is, of course, the theoretical dark matter but we don't even know if that actually exists. Even if one were totally blind there would still be light/energy. One could still feel infrared radiation, which is just another name for heat, at the very least:) And the shorter, dangerous to life radiation would still have an effect. Microwave and longer wavelengths are thought by some to have an adverse relation to emotional states, possibly causing depression. There are other ways to see aside from eyes, that (mostly) receive visible light.
Light. Life cannot exist without the Sun. .
You do realize that only the people who like dark will answer this right? Dark
