      Hi Lola, I too have thought about the same question before. My answer is I certainly hope so. Even though there has been no concrete evidence so far, I think its rather arrogant to assume that in this big, big universe with millions of planets, earth is the only planet harboring life. What do you think? 🙂

      A huge question! The age of the Earth is over four and a half billion years old and that is only a fraction of the age of the universe. We cannot even say how large the universe is so you could say it is beyond massive! So the chances that we are alone in the universe has to be fairly small. There is also much work on finding planets around other suns that orbit their suns within the ‘goldilocks zone’ – not too far to be too cold for life and not to near to be too hot. For a lot of work, see the Kepler space programme that has generated data suggesting there could be billions of such planets in other parts of the universe that could exist within these habitable zones around other stars, like our sun. For more on this quest, see: https://exoplanets.nasa.gov/resources/323/goldilocks-zone/. Closer to home, the search continues to find life elsewhere in our own solar system – europa, one of the moons around jupiter for instance – but microbial life, not aliens like in sci-fi!
      On the latter point, the search for complex life as seen in sci-fi is ongoing too – see here for the search for intelligent life on other planets by SETI: https://www.seti.org/

      Yes definitely! And I hope that they’re green with antennae! I think there has to be something else out there living in this giant universe 🙂
