In "A Short History of Nearly Everything," Bill Bryson explores the essence of life and existence, suggesting that all living organisms serve a purpose simply by existing. He highlights the idea that even the most basic forms of life have intrinsic value and contribute to the broader tapestry of life on Earth. This perspective prompts readers to reconsider the significance of even the smallest creatures in our ecosystem.

David Attenborough echoes this sentiment by emphasizing that the existence of life, regardless of its complexity, is a testament to a profound reality: life persists for its own sake. This notion invites reflection on the interconnectedness of all life forms and the beauty inherent in their mere existence, encouraging appreciation for the world around us and the diverse organisms that inhabit it.
