Are immortal people real

Answer 1

Immortal people, in the sense of living indefinitely without aging or dying, are not real. While certain organisms, like the Turritopsis dohrnii jellyfish, exhibit biological mechanisms that allow them to revert to earlier life stages, humans cannot achieve true immortality. Advances in medicine and technology may extend lifespan and improve health, but the concept of immortality remains a topic of Science Fiction and philosophical debate rather than scientific reality.
