The Earth being a giant computer/organism?
Lately I've been reading the Hitchhiker's guide to the Galaxy, which states that the earth is just a giant computer that was controlled by mice that were looking for the ulimate question to the ultimate answer; (the ultimate answer being of course 42) and before that I was looking up the Gaia Hypothosis, which states that the earth is just a giant organism and we [humans] are just cells or something like that. (like all our different cells making up us, or different types of ants making up an ant hill)
What are your opinions of these two theories and what do you make of them?
