Extraterrestrial civilizations. What is your opinion?
For all respected forum members, I would like to point out that the words "I haven't seen it, so I don't know" are foolish and do not serve as valid proof. Let me explain why. Tell me, have you ever seen the planet Earth from space? No? Then you don't know if it exists! Oh, dear! What a tragedy! It turns out that we probably don't exist either. :eek: And have you seen the vastness of the Universe? No? Then you don't know if it exists. You see, people used such words in the time of Galileo.
