we know that a planet must be a certain distance from its sun, relative to the size of that sun and its radiation, and that a planet must have a certain type atmosphere­, possess certain type of gases, contain certain elements within the planet's core, etc., for various life forms to eventually flourish..­. this is part of the story of our planet. but if the broad, initial parameters­, axis angle of the earth, the moon, atmosphere­, etc., were slightly different the whole structure for life would collapse. if the general requiremen­ts for complex life to form are so narrow, then so might the progressio­n of advanced life forms be, therefore, it would seem more likely that an alien from some very, very far off earth-like planet would be somewhat similar if not exactly like us.
