According to my imaginary friend

I have a friend
who says he doesn't believe in God
because he can imagine a world without Him

Okay

So if I believe my friend
then I should not believe him
since I can imagine a world without him
and therefore, according to him... he doesn't exist...?

I know my friend exists
(though I can't say much for his logic)
Why would he rather accept the ridiculous (reasoning)
than acknowledge the obvious?
What great lengths will he go to
to convince himself there is no God?
How long will he live in his imaginary world
instead of accepting reality?

Logic and evidence
point me to the existence
of both God and my friend

May they do the same to him.
