Along with many of their arguments and what they believe is proof, my all time favorite is how they look for gaps in science and think AH SCIENCE CANT EXPLAIN X IT HAS TO BE RELIGIOUS!
Another one I like is "science can't prove there's no god" this obviously works both ways, but the big difference is that science attempts to provide solid proof whereas religion relies solely on faith and very little proof.
I am a person who loves my faith yet I also enjoy science. Religion, in this day and age, is not about explaining the wonders of the universe but about the worship of God. I've never said what you say, that "science can't prove it so it must be religious".
Faith is about just that: Faith, not proof.
