look, this universe is always expanding. The perfect place for life is a planet like Earth. The Earth Is not to far, nor to close to the sun. The atmosphere fits our needs to breathe and survive. The Earth's gravitational pull is at a perfect balance. If not, we are either floating away from earth, or being crushed by nothing. Some planets meet most of these requirements, but some may not. Some we have not seen have got to have all of this. Why have a huge area of beautiful colors, sights, stars, Black holes, and maybe unusual things we have not even thought of, if not a single soul can view it? I am sure there are other planets that can have what Earth has, somewhere out in this mysterious universe. Humans say there is no other life other than on Earth. Simple Humans. Even I cannot official say yes, there are other life on other planets. This universe's doors to unknown knowledge is locked, yet the doors are right in front of our eyes. I do believe there is other, more complex life somewhere.
