Easy.
Disbelieve in God and, bingo, no more God!
Just ask Richard Dawkins.
The next problem is getting the religious people to believe in you....
Anyway, you have no problems with thinking about ways to kill God or the Devil. The Devil doesn't care and God will forgive as you don't really mean to do it anyway.
What about the Babel fish though? Such a staggering useful animal which could surely not have evolved by chance that it's used as the ultimate proof of the non-existence of God.
The argument goes something like this:
I refuse to prove I exist,says God, because proof denies faith, and without faith, I am nothing.
Ah, says Man, but the Babel fish proves you exist doesn't it, and therefore by your own argument, you don't.
Oh, says God, and disappears in a puff of logic.
That was easy, says Man and goes on to prove that black is white and gets killed on a zebra crossing.
As ever, Douglas Adams had it sorted.
