I think that for one who believes in a creator- it makes sense to conclude that the creator will be involved with alien life just as well as our own.

I think this is a Wise Move on the part of the Catholic Stance.

In asking questions about the origins, one will ultimately come to those they cannot answer at a given time.
At some point, we may well be faced with alien life forms. I think it's important that we respect them whether they be microbes or highly advanced species.

A large religion taking the stance that they are "like us" is far preferable than one that declares they must be of (Bad devil dude name here). Which many are doing.

I've crossed the line at this point.
