So, let’s assume we discover other life out there in the universe. Let’s assume that the other different intelligent species we discover are emotionally compatible with humans (i.e. we think in similar ways). I appreciate this is a stretch. Assuming religious organisations survive the discovery of life beyond Earth, would those religous organisations which refuse to accept same-sex marriage be okay with different-species marriage as long as the two intelligent life forms asking to be married were of identifiably opposite sex?
Maybe I think about this too much.
Or maybe I’m playing too much Mass Effect 3.
