I don't want to get into theology too much...but the existence of alien intelligence would by default invalidated the Bible as supposedly we Humans have been "created" in the image of God and of all things in creation we are most like "Him".
Some interesting books that tried to approach religion and aliens.
The Sparrow (novel)
A Case of Conscience.
The Catholic Church has tried to dance around the dogmatic aspects of it all repeatedly. Tho a massive philosophical question is tied to the definition and understanding of Consciousness. For Catholics it's relatively easier as they don't believe in a literal interpretation of the Bible.
Anyways. Don't wanna get into the religion thing.
