Prove your god
I do not recall who proposed this question or the exact wording but it was always one of my favorite questions to watch theists attempt to answer. Honestly as far as I am concerned this is a very simple question to answer but I like to see how others answer. The gist of this questions is :
A being appears in front of you and says I am God. What do you require for proof?
What do you tell / ask this being?
I can explain it to you but I can't understand it for you.
You see that evil will always triumph, because good is dumb.
