There was no concrete evidence of Immortal Cultivators in the real world because Immortal Cultivators were a fictional cultural concept that usually appeared in fantasy novels, martial arts novels, movies, and other works. Immortal cultivators were usually described as those who improved their physical and mental abilities to reach an extraordinary realm through practicing magic and internal energy. However, this concept contradicted the laws of physics and chemistry in the real world, so it was impossible to exist in reality. Although the stories and legends of the Immortal Cultivators inspired many people, they were just fictional fantasies and should not be regarded as real things in the real world.
