I think it is likely there's life just in our solar system (or has been - perhaps not currently extant). I think it's highly likely there is/has been life elsewhere in the universe.This questions is mostly directed at atheists / agnostics. Do you believe that there is life anywhere in the universe other than on earth?
If so, why?
If not, why not?
Now, whether that life is currently still extant, exists in a form our current science can recognize, or exists in a sapient form, that's much more up for question/speculation
