Ok then, are we talking intelligent life and if so what level?
Very good question. I think its arrogant for humans to believe we qualify as intelligent life; yes we are self-conscious/aware (and so are dolphins) but probably not clever at all...considering...:
Man took what 4 mil years to evolve into modern ("intelligent") man, modern man has been around for a 100k years, compared to the universe that is a few billion years old.
So if modern man took 100k years to become as clever as we are today, imagine an alien race that had a couple million years or even a billion years

head start on us. They might regard us as we would regard bacterial life forms if we discover such life forms on other planets. I shiver when I think what we would do to such life forms and therefore what these "real" intelligent aliens will do to us.
So, yes I do believe in aliens, but am not thrilled with the prospect of meeting ET.
