Read this in one of my new books today: Maybe the Earth is just a small molecule in an immense being, and maybe the animals and vegetation on Earth are all just germs and bacteria that live on that being, more or less in balance. Except for humans, who could be a dreaded disease that could destroy the being. Then maybe human diseases like plague, TB, and malaria, etc are actually medicines taken by the immense being trying to cure itself of its disease, which would be humans. It's not clear who is winning.
