  1. This assumes that intelligent life would arise similar in terms of our own and our intelligence is questionable as despite our scientific knowledge we live in a world fueled by the collective belief in an intangible concept for which we will work ourselves to death, kill, steal, go to war over. I'm talking about money which only has the value we give it but we are willing to ignore the signs of our own self destruction in order to get more of something we cannot eat, drink, make tools or clothing out of, etc... But I digress, with the age of the universe we could either be late or early to the party. Another world or worlds of the countless number out there could have had a series of events that saw an intelligent species arise a million or a billion years before now. We went from simple villages to landing on the moon in under 10,000 years - a mere blink in geological time - and the greatest leaps were in the last two hundred years. Only a thousand years ahead of us currently would put them way ahead of us in ways we can barely imagine. Conversely, if the universe lasts 120 trillion years as some suggest, the 13.8 billion years the universe has existed up to now will seem an incalculable eternity ago if an interstellar civilization arises somewhere in the Universe in 50-100 billion years from now. By then we'll be long gone along with our solar system with little trace of us ever having existed unless someone bumps into one of the Voyagers and plays our greatest hits.
