A Joke for Atheists

Apologies to my religious friends, but this was too funny.

Since my teen-age years I've used the following to explain how I arrived that there is no God.

A is A. (A being defined as EVERYTHING.)

Either

A has always existed. (Inconceivable)

or

A comes from nothing. (Impossible)

Following the dictum of the great 19th C philosopher Sir Arthur Conan Doyle "once you've eliminated the impossible, whatever remains, no matter how improbable, must be the truth."

Since A coming from nothing is impossible therefore A has always existed.
