      No I don’t. The universe is so big, it’d be very strange if we were the only ones here.
      Maybe as a scientist, you’ll be able to research ways to explore exoplanets to find signs of life?

      No I don’t think so! In the Milky Way alone there are billions of stars, and astronomers think that most stars have their own solar systems .. that means potentially billions of planets around other stars in our galaxy alone! So lots of opportunities for life to evolve! Scientists don’t really understand how life would look on other planets. Astrobiologists study life on Earth and try to understand how it started here, and look for other places in the universe with similar conditions.
