The phrase "I know that I know nothing" or "I know one thing; that I know nothing", sometimes called the Socratic paradox, is a well-known saying that is derived from Plato's account of the Greek philosopher Socrates. The phrase is not one that Socrates himself is ever recorded as saying. (Wikepedia)
Do divine beings exist?
1) Believers/Creationists: God exists.
2) Agnostics: I don't know.
3) Atheists: God does not exist.
JG: I include myseld in the #2 group. It can not be proved or disproved that there are divine beings. I believe in those things that I can touch and see.
