the universe is infinitely expanding in size, and we as humans have just barely begun to know our own solar system, let alone know our galaxy and we are far from knowing our universe. We are not alone in the universe, and believing so is foolish. To believe that we are the only planet that life decided to spring up on in an infinitismal void, amongst trillions of planets and galaxies, is short-sighted and you probably still think Santa exists.

There is no way that we are alone in the universe, there are other life-forms out there, and on our planet as well, whether you want to believe it or not. The truth is out there, its just up to you to accept it.
