      It’s impossible to say at the moment, but there’s over 100 billion planets in our galaxy alone, of which perhaps 40 billion may be able to potentially support life. Given those odds I’d be surprised if there isn’t life on at least some of them.

      Whether there is intelligent life, let alone alien civilisations, is a more tricky question. Certainly there isn’t an alien civilisation that has spread throughout the Milky Way, because we would probably see some evidence of a galactic civilisation, if it existed.

      I don’t know, but statistically speaking is possible.
      In the universe, we have not found anything that is unique. So, why would life be an exception?
      Nonetheless, it’s possible we would never manage to find it due to the vastness of space and our limited exploration capabilities.

      I believe that there is life on other planets because it formed so early on Earth. Life has probably existed on earth for 90% of its history!

      I am less optimistic we will ever find civilizations like ourselves since we do not see any evidence of them at all! If you are really curious look up something called the Fermi Paradox.

      Hello,
      I believe that yes. Somewhere so far that maybe we’ll never ever discover it can be some life. But which kind of life? Similar to humans by its advance or rather to prokaryota? That is very interesting!
