You're right. It's more rational to beleive in something that has a bit of evidence than none at all. However, let me ask you this: when you die, are you ever punished for beleiving? No! If there's no afterlife or your beleif is wrong, you're treated the same as everybody else. However, if your beleif happens to be right, you'll be rewarded. It may be a fairly small chance, but it's a chance. However, atheism completely gives up the chance of an eternal reward. Either you're right and there is no afterlife, in which case you're treated the same as everybody else, or you're wrong and you go to some kind of hell. Either way, the afterlife is 100% shit for an atheist, while a theist has a bit of hope. Again, beleive what you want to beleive, but I find it more logical to beleive in a God.
