If God is Incomprehensible...

For the sake of discussion, let us assume there's a god.  And let us further assume that god is incomprehensible.

If we were to now ask the question, "Does god exist", whose notion of god do you suppose would be closest to the truth:

• The Theist who has an idea of god and thinks his idea represents something that exists?
• The Atheist who has an idea of god and thinks his idea represents something that does not exist?
• The Agnostic who has an idea of god and thinks his idea represents something that he is uncertain exists?
• The young child who has as yet no idea of god and consequently cannot even understand the question?

Any opinion?
