This universe is millions and millions and millions and millions of light years in dimensions, and still expanding! There are hundreds and thousands of stars, planets, satellites, asteroids, galaxies and solar systems in our Universe. This amazing truth makes me believe that, somewhere, in some distant place, far away from here, or very near perhaps, there exists 'life', and it is even possible that it is 'intelligent'!
If you are someone who thinks that this belief is not nonsense, then read on. If you are not, feel free to criticize!
