The titular creature of the Alien series is one of the greatest movie aliens of all time, but how realistic is it? Obviously the filmmakers and H.R. Giger were not setting out to make a hard science fiction film, but just for fun, let's imagine that they had. What changes would need to be made to make the creature plausible? Discussion of how real aliens may appear is obviously speculative, but we can make educated guesses informed by an understanding of evolution and the history of life on Earth. The laws of physics apply everywhere in the universe, and the fundamental principles of evolution are likely to apply as well.
