"Why don't you believe in Santa? He believes in you!"<quoted text> Why, seriously, the evidence is overwhelming to me, and the fact that a fairy tale is to be believed by children, not adults. It's impossible for an adult to believe a known fairy tale as anything but a fairy tale. Why would an adult "desire" to believe in a fairytale, it's beyond normal reasoning to believe something that is totally known to be a fairytale. The bible is only said by atheists to be a fairytale not by anyone but atheist, which is common. When atheists were a child they believed in the fairytales that were mentioned until like christians when they came to be an adult stopped believing. Atheist believe in what God has created rather than the creator and he mentions this would happen long before it did. So believing in fairytales an adult isn't normal behaviour, but believing in God as an adult who tells us everything from the beginning of what was created and why and what to expect after death and everything in between. God didn't make it so easy for one to believe because our minds are meant to be used. If God made it clear that he is real then of course everyone would believe, what good would that be if it was simply given to you instead of showing God your ability to think and reason, it wouldn't be and you simply would be a robot. If there were no God your choices wouldn't matter except when breaking the law which then you would pay for your bad choices, I guess you would like no law also? God exsist and we have a duty to make a choice, our soul depends on it to believe and live the way he wants us to in his world he created for us. When you can prove he doesn't exsist like you do with other things in science then change will be obvious, without a doubt, life will be totally different from what it is now.
Essentially, this is the same argument you are using with regard to your God.
When you start to employ your ability to think and reason, you find that there is no difference between the evidence for Santa and the evidence for your God.
"Fables should be taught as fables, myths as myths, and miracles as poetic fancies. To teach superstitions as truths is a most terrible thing." - Hypatia of Alexandria (370 - 415 AD)
"Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blindfolded fear."
"I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue. But much as I want to believe that, and despite the ancient and worldwide cultural traditions that assert an afterlife, I know of nothing to suggest that it is more than wishful thinking. The world is so exquisite with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there's little good evidence. Far better it seems to me, in our vulnerability, is to look death in the eye and to be grateful every day for the brief but magnificent opportunity that life provides." - Carl Sagan
