We know that the first planets and stars were formed about 400 million years after the big bang, so about 13.3 billion years ago. So potentially there could be life forms out there over 3 times more evolved than us. Them looking at us, would be like us looking at single cell organisms. No wonder we havent had any contact yet.
Ok, so we 'guestimate' that the Universe is ~13.7 billion years old, Earth ~4.7. Life has taken ~4 billion years to produce us. Knowing this, could we make a very crude calculation as to what the chances are that there are life forms in the Universe more evolved than us?
What % of the planets/moons in the Universe have an environment that can sustain life? What % of those planets have had life evolving for more than 4 billion years? A lot.
@HabloIrlandes Don't know why you refer to the approximate age of the universe of 13.7 billion years as a "guestimate". It is nothing of the sort, rather it is known to a very specific value of error. Also, take care not to think of evolution as leading towards something, or necessarily heading towards ever increasing complexity. Reading a little Steven Jay Gould should hamper this tendancy. Quips like "more evolved" are misleading at best.
@Darwin42ME Thanks for the reply, by saying "guestimate" I meant "Approximate", but that's me trying to infuse a little humour into the comment, What titles would you recommend from "Steven Jay Gould"?

The only i want to hear, is that, all the sounds im listening, right now, behind this conversation, will never stop, and all that green, in that interview, will never desapear. I want to belive, but i want to live too. and try to save the planet.
thanks Brian Cox, for to leave me live, in peace. please, dont continue wiht that experiment. THANS VERY MUCH.
now im watching Brian Cox videos!

@HabloIrlandes thats exactly what i think even a million year headstart and look how far we'll be

that's actually the most interesting argument i've heard as to why there might not be life elsewhere
