If life exists outside the solar system its not automatically demonic. Bacterial lifeforms of course aren't demons even alien animals couldn't be demons.
The real issue here is with intelligent life forms. In my point of view there's only 3 possibilities.
1st: they are very intelligent animals but without a rational soul. So they'd be like koko the gorilla but with space ships. That wouldn't present no difficulty to the Catholic Faith because they'd be just animals like a cat or a dog.
2nd: they have rational souls and know God because he made some deal with them (there must be some biblical thing against this but I do not know). But if they got here they would consider us superior to them because we were made in God's image, the Son of God that is God Himself incarnated in a human being, and the Mother of God is also a human.
So I'd all be friends I guess.
3rd. Demons. They would come down here and tell everyone Christianity was wrong and they were our creators and shit and would tell us to worship them.
I take my bet on 3, no 2 must be wrong of a theological basis and I don't think animals can be that smart although its possible.
