When discussing issues like religion with people there are two very important first steps you must take to begin a successful discourse.
1. You must agree on the premise. If you can't even agree on the opening statement then everything that follows will be a waste of time since the person making the claim will just revert back to the premise and claim victory since you never addressed it.
It's like trying to argue with someone who says "I believe in the toothfairy". If you start by saying something like "you shouldn't believe in the toothfairy because there is no evidence for it." They will just respond with "well I BELIEVE it so it's true!"
The problem here is you didn't start with a premise that you both agreed on. A better premise in this situation would be to propose a question regarding the nature and definition of belief itself like "These are the rules I use to determine what I believe:" This will help establish why or why not the person would be justified in saying that they believe in the toothfairy.
2. You must define your terms! Many words have multiple meanings and there's nothing more frustrating in a discussion then people who use words incorrectly or constantly shift their meanings. Here's the top words that I see misused in religious conversation and what I propose the formal definitions should be:
Belief
Accepting a claim to be true. This can be done with or without evidence. I can believe that there might be aliens out there but I don't have any good evidence for them. I can also belief that my car will start tomorrow morning because I do have some evidence. It started almost every day since I bought it so it's likely that it will start again.
Knowledge
Plato calls it a "justified true belief" meaning that there must be substantial evidence before you can claim to know something. Also, knowledge is not 100% certainty. It's simply something that you belief very strongly because you've seen so much evidence for it. I can say that I KNOW the sun will rise tomorrow because it has done so for billions of years although I'm not 100% certain... The sun could blow up or something could cause the earth to stop spinning in it's orbit but I'm justified in saying that I KNOW the sun will rise because of the massive amount of historic evidence we have to support the claim.
Evidence
This is the trickiest one. There are 5 types of evidence:
1.Anecdotal evidence
2.Intuition
3.Personal experience
4.Scientific evidence
5.Testimonial.
The irony is that while testimony and personal experience is considered the most unreliable forms of evidence in court it's the most compelling evidence for religious believers.
When I define evidence I like to stick with the scientific definition because it's the only one that really allows us to verify the truth of a claim. So I define evidence as "Any objectively verifiable piece of information." I can't verify that you indeed saw a ghost last week and I can't prove that your gut feelings about aliens are true. What we should do is have everyone present REAL scientific evidence and form our beliefs based on that.
Faith
When evidence fails this is what people turn to. I define faith as "belief without evidence." This fits well with my previous definitions because you wouldn't need faith if you KNEW something because knowledge requires EVIDENCE and if you do have evidence then there's no reason to believe it on FAITH.
I run into a lot of problem with faith because people change the definition in mid conversation. They will say that they believe in God the same way they have faith the sun will rise. This is incorrect because they have massive amount of scientific evidence that the sun will rise tomorrow while they only have personal and testimonial evidence about God. It's not the same thing.
You can BELIEVE in God because of your FAITH but you can't say that you KNOW God because that would require EVIDENCE!
