I think that everything about the universe is amazing and interesting. I don't know how it's possible that some people can really believe that the only planet with life on it, is planet Earth. When you know about the existence of billions of galaxies, each galaxy having billions of stars, it's almost impossible that we are alone. I understand that many of those stars have planets orbiting around them. In addition, if we think that Earth is orbiting at about 150 million km from the sun, don't you think that many other suns must have planets at about the same distance and with similar conditions? I don't know you, but I'm sure that we're not alone!
Do you know any interesting facts about the universe? What are they?
