Do fundamentalists believe the Earth is the only life harboring planet in the entire universe or multiverse?

It always amazes me how people who claim to be rational and only believe what is scientifically proven will believe in just about anything except the existence of God! And then to totally make up stories about infinite multiverses and even dare to call that a scientific theory! I'll believe there's life somewhere else in the universe or some other universe in this infinite multiverse when there's a shred of scientific evidence to back it up. Sound familiar?
