In conversations with atheists, they may challenge us: “You’re claiming that God exists. Therefore, the burden of proof rests on you, not me. So … where’s your evidence?”
Atheist Michael Scriven insists “we need not have a proof that God does not exist in order to justify atheism. Atheism is obligatory in the absence of any evidence for God’s existence.”1 Or perhaps someone has told you that belief in God is just like belief in Santa Claus or the tooth fairy. Where do we begin to respond to such assertions?
First, define your terms — especially atheism. Understand the terms you are using. You can clear up a lot of confusion here and keep the conversation with a professing atheist on track. Ask your friend, “How do you define atheism?” According to theEncyclopedia of Philosophy, the historic definition of “atheist” is one who “maintains that there is no God, that is, that the sentence God exists expresses a false proposition.”2
The late atheist-turned-deist philosopher Antony Flew, defined atheism as“rejection of belief in God” — not merely the absence of belief in God.3 Likewise, Julian Baggini, in his book Atheism: A Very Short Introduction, asserts that atheism is “extremely simple to define.” It is “the belief that there is no God or gods.”4 By contrast, central to theism is that an infinitely good, wise, self-existent, and powerful personal Creator brought into being a creation separate from himself, though He sustains all things in being. This creation is comprised of things visible and invisible. And God uniquely made human beings with distinctive moral, spiritual, intellectual, and relational capacities.
