In Search of Another Earth: An Extremely Rare Planet,to the Earth should have almost all the conditions that favor life to originate and to evolve. But what are those conditions? We are so accustomed to live under this planetary environment that we often do not realize them. We are even not aware of many of the conditions that indirectly preserve our
