Spider-Man
Time
Time's longevity exists on an entirely different scale. Having commenced with the Big Bang approximately 13.8 billion years ago, Time has witnessed galaxy formation, stellar birth and death, and life's evolution from single cells to beings creating Spider-Man comics.
Time shows no indication of concluding. Cosmological models suggest it will continue for trillions of years until heat death renders further measurement academic. Time exceeds Spider-Man by approximately 230 million to one.
