  No, there is no definitive proof of life on other planets yet, but the James Webb Space Telescope has detected molecules in the atmosphere of exoplanet K2-18b that on Earth are produced by living organisms. While this is the strongest evidence yet for possible extraterrestrial life, it is not confirmation, as scientists are conducting further research to rule out non-biological explanations and confirm the presence of these biosignatures.
