      Unfortunately not 🙁

      However, scientists I know worked on the Winchombe meteorite, which landed in the UK in 2021.

      In this meteorite, scientists found water and tiny building blocks of life, which shows that meteorites might have helped start life on Earth.

      No, however some scientists back in 1996 claimed they found evidence of fossilised bacteria in a meteorite from Mars (ALH 84001), which was really controversial at the time! Ultimately they were proven incorrect. But like Joshua has said, we do find evidence of water in some meteorites (effectively trapped inside minerals) and other elements which are essential for life
