Earth is well equipped as a planet and ideally placed in our solar system and galaxy to support life as we know it. The product of some 4.6 billion years of cosmic construction, our planet is flush with life thanks to a fortuitous set of conditions. Earth is tilted with respect to the sun, and teeters as it spins.

At the beginning there was no life on earth, today you can study organic chemistry and inorganic chemistry, back then there was no organic chemistry…there was no life on Earth, therefore in no way could Earth be a living entity. Once evolution started up to where we are now, life came to be upon Earth, and we have organic chemistry and inorganic chemistry…there is presently life on Earth…you might conclude under that perspective Earth could be considered a living entity. If you broaden your perspective, life on Earth (organic chemistry) which came upon being much after Earth came to be, lives off what is inorganic, the basic non organic elements and molecules, meaning life on Earth lives off Earth and is just a parasite and is not part of Earth itself. If all life on Earth ceased to exist, Earth still would exist, having only the parasite life, dissapeared, therefore Earth as such is non-living. Again…if you extrapolate the substance of all matter living and non-living, to energy, then you may conclude that energy and not the organic or non-organic is what commands the definition of life. Earth then…if all organic life were to become extinct, still would be composed of non organic atoms and molecules, all of which have energy, and under that extreme extrapolation of the definition of life, you could conclude that Earth, as well as the entire Universe, are a living entity. Now…if the Universe reaches maximum entropy (heat death), then the Universe has only energy spread out evenly, but energy from which no work can be obtained, in this case and even though energy is still there, the Universe can be considered dead.
