I buy into evolution, and I doubt they would look anything like us. I also think there would have to be a little luck involved for an alien race to go through the evolution cycle and be more advanced than us. Because of planetary changes, asteroids and everything else that can alter living life, they have to go through perfect conditions over a very long period of time to make the kinds of advancements or more that we have enjoyed on Earth. With the melting of the polar ice caps, earthquakes, volcanic eruptions etc. there's probably a good chance that we'll never see the kinds of advancements that we see in all of these science fiction movies, where they travel from planet to planet. Human life won't be here long enough to make it that far. Not at the rate the earth is changing. And there is still those renegade asteroids out there that could hit us.I think they're unimaginable if you buy into science and evolution.
