Many IDiots like to claim that it takes more faith to be an atheist than to be a theist, often following up with all sorts of straw men about evolution and physics. Let's compare:
Creationists say the universe came from a magic man that randomly popped into existence from nothing with infinite power, infinite intelligence, and presumably infinite complexity to accommodate the other features. Oh, and that he randomly decided to make the universe look exactly like what scientists say it really is, and all to dick around with us.
Scientists have detailed, testable theories that obey consistent laws, detailing many of the steps, all the way back to the Big Bang. Before that, we don't know.
Which takes more faith?: That an infinitely complex, omniscient, omnipotent stone idol just popped in from nowhere, or "we don't know, yet."
