Also; the existence or lack of existence of any alien life form would have no theological bearing on the western church. (That’s not to say that it would in the east. I just am ignorant of the details -- though if I was a betting man I would say that it is the same in that case also.) Wouldn’t change a thing; and not because it would get “swept under the carpet” but because it really changes nothing core to the dogma deemed necessary for the western church (i.e. the Ecumenical creeds).
And, just as an even further aside, some prominent Christian theologians believe that aliens might exist.
And I think this news is still no proof for skeptical people (like myself). They found molecules that are very rare on earth and are now suggesting they originated in space:
"...but were unsure whether these materials actually originate in space. The presence of these three molecules, however, suggest that they do, potentially raising new questions..."
So just new questions and suggestions. No proof of alien life for me. But interesting!
Sure, an agnostic might be put into a further tailspin, but so what? Most of the world's faithful have already demonstrated the enviable ability to suspend any desire to investigate the mechanics of their belief system. What difference will it matter that aliens were thrown into the equation?
