You can't prove a negative. Science will never disprove any god. It's impossible. The same way you can't prove bigfoot, tooth fairies and leprechauns don't exist. You simply look at the evidence at hand and determine which hypothesis fits the best. A supernatural creator has no evidence to support it. This hypothesis alone creates an even greater problem because you then must explain the complexity and origin of the deity. The evidence of our universe, our galaxy, our planet and our species suggests there's not even a need for a supernatural creator. We have far more plausible hypotheses that have significant amounts of evidence to support them. Most atheists are not atheists for emotional reasons. They're atheists because they embrace, logic, and reason. Until there is significant evidence to support the god hypothesis, we shall remain in a neutral state and speak out when it's utilized in passing laws that suppress our fellow humans.
