Mass moved at in pretty equal density in the "Great Bang". IT's actuallu good odds that a Earth like planet exists in our own galaxy. How ever we won't recieve any "RADIO" sounds if they techologicaly advanceed the same, until the waves travel far enough. THey would have to be more advanced then us.

My take on this : Until we can put some better upper or lower bounds on ETI life in the galaxy, all this is pure speculating. Life is full of surprises, and ETI life in the galaxy is surely no
exception
to that. The lower bound right now is 1 planet. Upper bound is about 100 billion. Let's narrow this window...

Our star is a 3rd generation. Until now, maybe there just wasn't enough heavier elements around to build planets of a size conducive to life. Our planet is 4.5 billion years old. Life has existed on it for 3.5 billion years. Of that, 2.5 billion was devoted to single cell organisms. Only in the last billion years has complex life evolved. Maybe the happy accident that lead to complex life doesn't occur very often. Even AFTER complex life evolved, intelligence didn't automatically spring up. Dinosaurs were around for hundreds of millions of years, but there's been no evidence that any dinosaur species ever developed an intelligence sufficient to develop technology. Maybe the universe is awash in life, but its mostly single celled organisms. On occasion, it evolves past that, but seldom develops anything with an IQ above that of a gerbil or snake. Perhaps it's frequently wiped out by radiation from nearby super novas. Or life begins, but the planet it's on looses its stable orbit. Of all the life on our planet today, or that has ever lived, we are the only species to have developed enough to even build a mud hut. Maybe humans are just freaks of nature.
