1) "There is really no such thing as an atheist. Deep in their heart all atheists are just mad at God, but really they do think that he is real. They are just trying to ignore him, like a four year old will ignore people who make him made. Since everyone has to believe in God, he is real."
2) “There is really no such thing as an atheist. Deep in their heart atheists know that God is real, they just don’t want him to be real so they are not accountable to any higher authority. Being accountable to a higher authority makes them feel guilty because of their sinful lifestyle. This guilt is no fun when the atheists get together to crush unbaptized babies for Satan with stacks of Britannica Encyclopedias, smoke weed, rob banks, and try to invent new sciences that will spread the lies of secular humanist materialism. But even the staunchest atheist secular humanist materialist knows that God is real in his heart, therefore he is real.”
3)”Evolution is false, therefore creationism is true. Since creationism is true, and everyone knows that the only creation story that is not a wacky myth is the one from the bible, Christianity is real. We know that evolution is false because genetics proves that Lamarckism is false, therefore evolution cannot be real. Even Darwin renounced his theory, and since Christian creation is the only alternative answer that makes sense, it is real!”
(My apologies to Christians that take apologetics more seriously than most. I know that these sound goofy, but are paraphrased versions of real arguments that have been tried out on me.)
