Well, look at the numbers. I don't know how many planets we have in our solar system but think it's like 9 or something. Then how many solar systems are in our own galaxy, that's right, a hell of a lot more than you can count. And solar systems vary in size from probably tiny to diffinately larger than our own. So say the average size is that of our own. Well, 9 or so times oh, an estimated 10,000 systems. What are the chances of running into inteligent (not neccessarily advanced) life..... the numbers make me think that it's pretty good that we will eventually.
