Is Christianity more logical than atheism? I would say so.
The atheist cannot answer questions such as, "What is the purpose of humanity?"; "Where did the universe come from?"; "Where do the concepts of good and evil come from?"; and others.
The origin of the universe, I believe, is best answered by the existence of a powerful, creative mind that we know as God. The explanation for the impossible fine-tuning of the universe can best be explained by God. There are many attributes of the universe and our solar system that cannot be greatly changed without it either being unable to exist, or unable to be inhabited. It's more reasonable to say a creative mind did it than random chance. Our desires for purpose and hope can best be explained by the existence of God.
And perhaps the hardest thing for the atheist to knock is the life, death, and resurrection of Jesus Christ. If the Gospels were merely fiction or falsified in any way, well, the events that the Gospels claimed happened took place in very populated areas. The crux of our faith - the death and resurrection - took place in Jerusalem around Passover. Surely if it were false, there would have more than enough people around to say "It didn't happen!" and Christianity would have stopped in its tracks. But in fact, the Resurrection is basically impossible to disprove. The existence of Jesus and the early church are verified by historians, governors - and even satirists. I can think of no reason, outside of theological or philosophical bias, to find Christianity to be less logical than atheism. To be an atheist, you need to assume you know enough about the universe that you can reasonably say there is no God. But how can anybody seriously make that claim?
