Aliens are stereotypicaly characterized as creatures that are not on earth. But hey can exist. There is no technology to prove it, only theories. They can livein our world, yet we might not see them because they are vibrating too fast that we can't see them. So basicaly, there might be a world within our world. I met an astro physicist once.
