Can atheists convert theists?

[Knight]

All I know of God is the concept of a "deity" as with all I know of the Easter Bunny is the concept of "The Easter Bunny" - I claim no knowledge of the Easter Bunny... I just reject its existence. As with God.

But there are specifics about the attributes of both which are included in each, intentional or not. What exactly is "God"--a "deity?" --and what is a deity? It is a supreme being. And what does that mean? Using definitions alone we are already divulging into territory we should not. This sets up the common flaw of looking for what we are defining instead of defining what we are finding. Rejection the notion that something which has not been observed, measured, or detected exists is meaningless.
