Many of the people in world believe that Alien life exists. There are also many evidences related to alien life, extra terrestrial way, warm hole (from which they can travel through galaxies). What's your view on alien life. Does it even exists? Or it's just a rumor.
Probabilities alone indicate there is a high probability there is extraterrestrial life in the universe, whether this life is intelligent is another matter, the most abundant life in the universe will come in the form of bacterias and stuff like that.
