Do you believe the Earth is "alive"? What does that mean to you? Do you believe the Earth is actually a living being? Or do you believe so metaphorically (such as "Mother Earth")? Personally, I don't see any of these theories being more than poetic. It's a neat thought but I can't see it holding any weight. Seeing as we really don't have a clear idea as to where and how life started, I think it's fairly silly to believe the Earth is a "mother" of any sorts or that it is even the slightest bit sentient. That's just me though, I'm interested in hearing what people think.
