Everything From Nothing?

Creationists like Ray Comfort are always criticizing evolutionists saying that it is intellectual dishonesty to teach that life and the universe came from nothing. However on the same note creationists teach that God created everything from nothing, pretty hypocritical of them when you think about it. The only difference they see is that God is the agent by which all existence was created out of absolutely nothing. But that does not answer the question where did everything come from? Being a former creationist myself I understand the futility of asking where did God come from? Because God by definition created beginnings and is not in the category of things that begin, therefore does not need a beginning himself, so I will not make the mistake of jumping on that train with other naturalists. But that does not excuse the claim that God created everything from nothing, the same thing that creationists say is impossible. So what did God use to make everything from nothing?
