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.
Sure it's all rumors. I don't think there is any documentary evidence of the existence of extraterrestrial civilizations, but in itself this may not be proof they don't exist. Big universe and civilization may well be.
