You know, there's so much wishful thinking on this subject that it's just ridiculous. Future generations will marvel at how the
desire to believe in life besides our own was so continuously translated into hopeful-sounding "science" like this that makes it seem like life should be behind every rock in the universe.
Oh, I guess I'm raining on somebodies' parade. But really, life is interesting enough without indulging in such fantasies (at taxpayer expense usually).
