Best Argument Against the Existence of God = SHARKS!
Sharks have to be like the strongest argument against God ever.
That's right, you heard me, sharks.
Just ask yourself, what kind of *all loving God creates a blood thirsty, razor blade like saw toothed monster fish, a veritable killing machine none-the-less, and puts it right dab smack in the middle of where we all like to swim, boat, and have a leisurely time at the beach with the family.
Hell no! Sharks are proof that God doesn't exist. At the very least it proves God hates you. Sharks he's fine with. Don't blame the messenger for pointing it out. Blame the damn sharks.
