Look at the stars
I was walking through the nature trail the other night. It was dark, and there were no lights. Just the light from the stars in the sky. And I thought how different life would have been if we did not have lights at night.
How would you feel if you woke up at night in a forest?
How would you feel if you woke up in the same forest at the same place, but in the morning, when there's light?
I thought back to that scene in the first Avatar. Where Jake Sully is alone in the forest at dark, scared of everything and how it transitions to him seeing the beauty of the jungle at night, as he gets better aligned with the jungle.
It's evolutionary, this fear of dark places.
Places and times, change how we look at things. The world looks different. What if we could see outside the visible range. Would we have been scared of the dark then?
