Fiend God
You read it both times, but you are still asking someone else (me) what it meant?
Take this example:
Person 1: Do you have any evidence that this "gravity" thing exists?
Person 2: Are you seriously asking me to prove to you that things fall towards the ground?
It's not that person 2 didn't understand. It's that person 1's question is so silly and ridiculous, and would indicate such a profound ignorance that person 2 doesn't believe the question is genuine.
