Light or Darkness?

There are creatures that are blind, living and hunting at night. They don't need the sun or light as such. Also, I want to remind you that initially, there was only darkness in the Universe...

These creatures will die from the cold and hunger (there is nothing to hunt), they will only last longer than the others. As for HOW to bring light – that is a personal matter for everyone. For example, I would sacrifice the interests of hundreds of people to save thousands.
