Science has found other ways to create life. Instead of carbon based life forms I think it was phosphorus (can't find the article from nearly a decade so I'm prob incorrect about the element). So I think they are interested in those conditions as well but as many posters have already stated, we know life exists under these conditions so let's see where else these conditions exist. But you don't hear from the other end of that very often because not a lot of progress has been made there. Keep in mind they work off grants primarily for funding. No results usually=no more $$. So it's gotta be difficult to research things that seem far fetched.
