Theist "You are Evidence" argument.

[brewer]

Why would you try to combat a statement that isn't an argument? You need to ask for elaboration before it can even become one, and then you can combat.

Usually when I ask for an explanation I get them repeating what they said and asking if they stuttered. :/

I'm with Alex. "You are evidence" is simply the belief without proof. Repeating themselves only demonstrates their limited reasoning ability. Might want to terminate the discussion at that point.
