Obviously. The fact is, there are an infinite number of things that do not exist, from pink snorklewackers to purple unicorns to George Bush's IQ. Because the list of things that do not exist is infinite, the only logical default position is that "A" does not exist until ample evidence is supplied to suggest "A" does indeed exist. If you claim to have a car that runs on french fries and waffles, there is absolutely no burden on me to prove you do not. It is entirely up to you, the person making the affirmative claim, to prove you have such a car. If you don't offer any evidence of said car, I can only conclude it does not exist. But I am certainly open to changing my mind.

As an atheist I am not stating "God does not exist". What I am stating is "To date I have seen no evidence to suggest the existence of a God." Same applies for your french fry and waffle car. I don't know for a fact it doesn't exist. I just haven't seen any evidence it does, so I don't believe it exists.
