Christianity IS Geocentrism.

[Angrboda]

I don't know that you've moved the question away from the concept of earth being the spiritual center. Maybe the rest of the universe is sterile rock and plasma; maybe it isn't. At this point, we just don't know. Until we have a better idea about what conditions are necessary for the origin of life as we know it, we really don't have a sound basis for speculating on the odds of life as we know it occurring elsewhere in the universe. Given that, comparisons like Drake's equation are just a crapshoot. What is your attachment to the notion, in certain religions, that life here on earth, specifically human life, is special? For all we know, it may well indeed be. Probably not, but until we actually know, what's the point in getting out a bugle and doing a dance?
