Zombies and skeletons, in the forms commonly depicted in popular culture, such as animated corpses or animated skeletal structures, do not exist in the real world.
Skeletons are real and are the internal framework of bones that support all vertebrates, including humans. However, they do not have the ability to move or function on their own as they are just the bony structure without any muscles, nerves, or other tissues needed for motion.
Zombies, as portrayed in movies, TV shows, and books, are fictional creatures. They are often depicted as reanimated corpses that have risen from the dead and attack the living, typically through biting or other means of transmission. These stories come from a mixture of folklore, mythology, and modern storytelling but do not reflect any scientifically verified phenomena.
