      Hi skyebroadband,

      That is a deep question! I am not a physicist or an astronomer but I don’t think they would have the answer either! From what I have read it is highly unlikely. There are 500billion stars similar to our sun and 100 billion billion planets similar to the earth in size and distance to their star (estimated obvs). However, no-one has contacted us! Where is everybody? This is something that you can read more about, it is called the fermi paradox and tries to explain why we haven’t heard from any space-neighbours. There are many possibilities to explain it, like they are super intelligent organisms and to them we are like ants, they are speaking but we can’t even pick up that they are talking!

      (as you can see I like the space even if it’s not my topic).

      Hope that has answered your question
