Stephen Hawking - Aliens

Well most of the idea behind searching for other life, in my eyes, is that if we find other life elsewhere, we find other places which can support life. I definitely think our focus should be on figuring out how we can get at least some of us off of this ball of dirt. We're essentially keeping all of our eyes in one basket, and if that basket drops the human race (as well as all life as we know it, potentially) is gone.

You're right though, past that there isn't really any value in finding other life, unless it is advanced enough that we can learn from it in some way. But honestly, I think the same could be said about any sort of space exploration, and a lot of science and research in general.
