@leaning agnostic doesn't belong with atheist, Deist, Or theist. Atheist, Theist, And theist answers the question "do you believe in a god? " And gnostic and agnostic answers the question "is there a god? "
I'm just a layman regarding religion, But should I Google Agnostic, First result that pops up for me is,
"a person who believes that nothing is known or can be known of the existence or nature of God or of anything beyond material phenomena; a person who claims neither faith nor disbelief in God. "
