To a Nontheist an example would be unnecessary and by making an example it would then be moot.

Tim: Zack, is that your exgirlfriend?
Zack: No, she's an expotential. We never actually dated...

Theist: God exists.
Nontheist: Prove it.
Theist: Well, just look around you. God created everything you see. See? That proves God!
Nontheist: I see...and how do you know that everything wasn’t created by an invisible purple Gnome named Wilbur who lives on the dark side of the moon, therefore proving Wilbur?
Theist: Because fill-in-the-blank-holy-book says that God did it!
Nontheist: Just how do you know your book’s claims are reliable though?
Theist: Because my book is self-authenicating, it says right here that it was written by God.
Nontheist: Using a book that claims self authentication commits the logical fallacy of circular reasoning. Extraordinary claims require extraordinary evidence. Assertions that are unfalsifiable and immune from disproof aren’t worth much. How do you know your book wasn’t written by the Invisible Pink Unicorn?

To be a true nontheist, one must come to grips with the reality that this is probably the only life and existence they will ever know.

All atheists are nontheists, but not all nontheists are atheists.

"Yo do you believe in god?"
"Nah, I'm a nontheist."
The conversation thus ceases.

christian: God bless you!
nontheist: Thanks, I guess. You too.

christian: God bless you!
atheist: Ha, you still believe in your bullshit cult?
