  The things in the universe are currently spreading out, so in that way the size of the universe is becoming greater. If there are enough stars and planets around, then the probability of one similar to ours could be high. I’m not sure if the universe is that big, but how can we tell?

  I don’t think that you can say that it’s more than likely. The reality is that no-one knows what there was before the big bang, and no-one knows what will happen as the universe ages: either it will keep expanding, or it will begin contracting. There is some debate amongst cosmologists about which of these things will happen, and they are working hard to try and understand it.
