“Are there other intelligent life forms in the universe?” This is one of the famous questions that you have asked yourself or heard many times being asked by scientists. The idea beneath this narcissistic point of view is that we think the ultimate purpose of the evolution is to form intelligent life forms. Whereas if we were living not so long ago, say 150 million years ago, we might have thought that the purpose of the evolution is to form dinosaurs with their huge bodies and unopposable forces.
