What is the most difficult question or argument you have received from a theist?
Or if none, what’s the most ridiculous?
This ignorant request. "Prove to me that there isn't God". Thing is, how you reason with people who hold unshakable believe in creator? We may dismiss their arrogance and move on; only problem is that their activities, actions affect our lives irreparably.
I think you really struggle when Christians talk about the existence of God that is confirmed in their hearts. It's where religion and psychology meet and separate at the same time. For the Christian, the heart is where the person and God meet. For the atheist, it is where a person and his or her feelings meet. That's probably when the atheist and the Christian should agree to differ.
"I like to beilieve that there is something after death." It is not exactly an argument. But it is a comment. I am uncomfortable with the thought of telling such a person that death may actually be the end. I believe I responded by saying that there is no reason not to believe that there is something after death. (Their may not be reason to believe it either.) It's a who knows kinda thing.
“Are you not afraid you will roast in hell”? They just could not grasp that it was a nonsensical question me as I don’t believe in the concept of heaven and hell. This was just typical of many questions I’ve had posed over the years, but you cannot have a rational duscussion with someone who is coming from the viewpoint of blind faith, not evidential argument.
