Ignosticism

Ignosticism is the belief that people should avoid taking a position on "the existence of God" until a concept of God has been defined.

Ignostics claim that the sound or row of alphabet letters "God" (with a capital "G") is meaningless because they lack belief that any coherent definition has been presented. They claim ignorance of any meaningful definition for "God" that has been given.

Ignostics claim that "God is what caused everything to exist that exists except God" is not only circular, allegedly defining "God" in terms of "God", but also gives no description for "God" since "what something did" is not "what something is".

It is sometimes considered synonymous with theological noncognitivism.
