is now extinct. Or, they haven't even existed yet. Our solar system is about 4.5 billion years old and the universe is about 15 billion years old. Yet human existence is just a nanosecond in comparison. Not to mention that we've only been able to communicate electronically for about a century. So, if anyone out there did try to communicate with us in the last 4.5 billion years up until very recently, we wouldn't have been around nor have the means to detect it. Or, maybe a star that's forming right now will develop intelligent life on it 4.5 billion years from now, long after our sun has died, and they'll never know we existed. But, with an infinite universe that is still developing 15 billion years after it was created, I would say that it's impossible for intelligent life not to exist at some other place and time somewhere else in the universe. There's no point, and there's no reason. There does not HAVE to be life on another planet, but it is possible. Chances are VERY slim that there's life on another planet right NOW, but there may be chance of a planet suitable for supporting life (still slim, but not as slim). Whats the use of this speculation?Surely you realise that any such beings are in a different time.Suppose we send a message with enough power to reach a close star(one in the milky way galaxy) so they receive it and being super-intelligent they send an immediate
