Why does discussion of lifeforms on other planets bring out the C/E debaters? Seems like there either is life out there or there isn't. One thing seems likely: there will be life out there and it will be us.
It's an interesting question. Let's assume, for argument's sake, that life exists out there. Let's even go further and assume that such life is sentient.
You don't have to be a theologian to realize that such a discovery would shake the foundations of all of our major religions.
