The spherical object we currently inhabit, is perfectly situated in its orbitary location to foster life - the carbon based kind, all living organisms that dwell this globe, have. Without an argument, life on this sphere began very very tiny and very very long ago - 3.5 billion years. Today, without a doubt a cool 3.5 billion years later we ourselves also appear on the face of planet earth. An extensively elongated succession of eons with precision laws of physics and mathematical constants at play, is all it took. This sphere having been fully colonized, is our only home, now and till the day we will be no more - rest assured, we ain't going nowhere else.
