No.
One of my mates is a religious nutjob. He believes anything which is not in the Quran is false and just does not exist. He believes dinosaurs are a figment of the American government (read "Illuminati"), created solely for the purpose of disproving Islam.
So even if they find E.T. life, the religious nutjobs with just think it's a conspiracy.
You should get you mate to join and start a thread on what he believes, it would be interesting to see how he reacts to someone who can use the Qu'ran to refute his interpretations and see how and why he has come to the strange conclusions he has.
