Guess what, it has already been shower that on planets other than earth, and solar systems other than earth's (that are nearby, btw), the "transition of chemistry into biology" has already been completed. What does that say about the odds? It says Hoyle was quite foolish, and spoke of something of which he had no real knowledge. And even if he is correct in his assumption (it wasn't a true theory, as it wasn't based in real observation or relating knowledge), the odds would still be quite in the favor of their being other life. You don't seem to understand the extent of just our one galaxy, do you? And our galaxy is just one of thousands, possibly millions, or more. There isn't anything to say that galaxies aren't tiny pieces of mega-galaxies (or whatever), either; and then millions of such mega-galaxies; or maybe those mega-galaxies are just tiny parts of even greater structures. It is quite a likelyhood that our universe is infinite. This would mean 99.9(with 9 repeating infinitely)% chance of infinite forms of life.
