      Hi 10thosamb,
      ooooo I like this question a lot.

      So scientists have just found 3 other planets in the universe which are the exact location from the Sun that Earth is here from our sun. This means everything like the atmosphere and the air and the water should be same, which is important for life.

      They have named this place the Goldilocks world – from the nursery rhyme or being not ‘too hot’ and not ‘too cold’. So there must be life on these planets.

      But maybe there could be life that doesn’t need what we have on Earth, which means there could be life in the 25 billion galaxies that we have in the universe…
      With that much space and planets – life must exist somewhere else.

      Bur have you seen the ‘UFO’ that was moving in and out of our volcano the other day – I don’t think a rock can move through the sky and stop and change direction…here the link to see this video 😀

      Hi 10thosamb,

      there probably is but we might not recognise it as life as it could be very different to us. If there is life out there I hope we never come across it as knowing human behaviour it would probably all end in tears.

      Hi 10thosamb!

      Well… we haven’t found it yet, but it’s quite likely, as we have found other planets with the right conditions for life to exist!

      Hey 10thosamb,

      I think there probably is somewhere out there, yes. We haven’t found it yet but the way we’re looking is very restrictive. We assume that other life in the universe requires the same conditions as us to live. Now, this isn’t the best way of doing things but there are so many planets out there that we need to narrow the search down a bit. That means we’re after planets a certain mass and a certain distance from a certain-sized star… so it’s easy to understand why we’re having trouble.

      It might be the case that other life forms aren’t anything like us – they might not be carbon-based for example. They might not even exist in the dimensions we know about. So, it might be very difficult to ever find them.

      One thing that always entertains me on things like Star Trek is that aliens from all kinds of different worlds always seem to have very similar technologies to us! That’s incredibly unlikely – if there is life out there it may be too unevolved to even look for us or so highly evolved that it’s technology far exceeds our own!

      Hope that helps,
