Aliens are a term used to describe extraterrestrial beings or phenomena that have not been identified as belonging to Earth or not. There are many different opinions about the shape, size, abilities, and ways of survival of these creatures. Some believe that aliens may have a shape similar to humans, while others believe that they may have completely different shapes, even with the ability to interact and use superior abilities than humans. However, there is still no clear scientific evidence of the existence of aliens.
