Roaches are here to clean up after sloppy humans. Something's gotta do it.
Us humans are gross too, but yet we're here also. Everything has a purpose somewhere on the earth. I'm actually seriously allergic to roaches, to be honest😂
Everything has a purpose. When it seems that purpose is failing it is usually because of man's mismanagement of things. The recycling system that was given us was perfect. The greed and the insistence on man's part to ignore his creator is at the heart of most of our problems.
... So we have something to point to and say: "THAT species will survive after a nuclear war. We don't want to leave the planet to THEM, do we? So let's try to avoid killing ourselves off."
