Is faith irrational? Do you need proof against something not to believe in it?
I am an atheist and my parents and brother are all hardcore catholics. So much so they make me go to church every Sunday with them despite my voiced disbelief. Today we had a debate. After about 20 minutes, I finally got them to admit there was no proof for or against the existence of a god. I then brought up the point that they were irrational because belief in something for which there is no proof is by definition irrational. Instead of trying to prove me wrong, they kept bringing up the fact that it would be just as irrational to believe there is no god when there isn't proof. (next paragraph) What do you think about this argument? Is it irrational to believe in something for which there is no proof? I would be just as irrational as them if I believed that there couldn't possibly be a god. This leaves us with which argument is more rational, the belief in a god or non-belief. They kept bringing up the argument that me not believing in something because there is no proof for it is just as rational as believing in something for which there is no proof. What they meant was that their belief in God and the bible was just as rational of a belief as my 6.9/7 on Dawkins' atheism scale position (that being the thought that you have to be open to the idea that there could be a god because there is no proof against). My argument was that because the burden of proof is on the person making the claim, it's irrational to believe in something until it's proven true and that not believing in it, but knowing that it's possible that it could exist is the most rational position. What do you think? Which one of us is thinking irrationally? I want logical, rational responses that either strengthen my argument, or prove it wrong.
(I posted this in the atheism subreddit, but I wanted to post it here so I could get both sides of the argument. I'm not posting this here to push my atheist ideas or anything like that, I'm posting it here because I'm open to the fact that I might be wrong and I'm giving you a chance to change my mind.)

It seems as though everything you are saying revolves around the concept of proof. The burden of proof, what supports proof, what disproves, and the need for proof to believe in something.
Proof, and the scientific method for discovering it, are all we have when it comes to matters of fact like trees, rocks, gases, evolution, etc. Proof doesn't mean a thing for subjective measures of value.
How does one "prove" that murder is wrong? Some atheists like to talk about purely utilitarian and humanistic systems of ethics. Murder is wrong because it causes pain, or because it causes social unrest, etc. But then, why is causing pain wrong? Why is disrupting society wrong? "Because then it causes people to suffer," they might say. Why is causing people to suffer wrong? At that point, there is often an appeal to the biological evolution of empathy. But we also evolved to dislike bitter foods - yet no one thinks that eating them is "wrong".
There is a difference between mere personal distaste and abstract moral outrage. But that internal sense of justice, without which we would be psychopathic monsters, is itself completely separate from "proof". Societies keep coming back to the Golden Rule, not because it "makes sense" - it doesn't, not by any practical standards, which is why it's such a big deal when someone comes along preaching it - but because something completely outside the scope of empiricism, something entirely within our subjective existence, tells us that it's what's Right.
