Its a scientific endeavor. They are observing the universe looking for evidence. So far it looks like there isnt anything out there but the universe is far more vast than could ever be searched by humans. I dont see where faith comes in. Many people involved in SETI believe there probably isnt any life out there but it doesnt hurt to look. People who are doing things based on faith usually dont want to observe the world because they feel it is a waste of time, since they know the truth already.
