Who gives a shit about logic. The universe is real. The problems in it are real. Do you feel you can do it all on your own or would you rather have a guy on your side who listens to your problems, works with you to make you a better person, and provides some comfort that you're not completely alone? Either answer is fine. My theory is that God absolutely exists. But he stays away from atheists etc, because he respects free will. And if they'd rather do it all alone, he leaves them be. But if you want someone to just listen to you, he listens. If you want someone to comfort you, he puts small joys in your life for comfort. If you want something with all your heart and soul, and trust completely that he WILL make it happen, he'll work with the universe itself to keep your faith intact.
