"i want to believe, i really do".
i do not want to believe. if i got proof of something, i don't believe it, i know it.
now with unprovable things, there are at least probabilities. if there is much evidence for something without any evidence against it, it's probability is pretty high. if there's no evidence whatsoever for something, the probability is pretty low. this is like poker. i don't know the other's hand, but i know the possibilities.
the problem with the "are we created" question is, that if answered positively for whatever reason, it leaves one with even more unprovable questions. i don't even want to begin listing some of the questions, because it leads to nowhere.
simply put: "we are (most probably) not created" and "we are (maybe) created, so what" are not much of a difference when it comes to picking one's morals or way of life.
on the other hand "we are created, it's been one single personal god who spoke to people in the bronce-age, told them to write books that do not really make a superhuman impression, revised most of the stuff later by sending his son to earth and let him die as a virtual payment to himself for a sin he himself invented so everybody who believes this can live forever" sounds a little far-fetched, especially when the person believing this thinks, everone who replaces "sending his son" with "coming down himself" is a complete idiot and everyone who adds a character named "mohammed" to the whole story will be killed by his loving god.
