According to Christian mythology, god created us and gave us free will.  But why?  No one can claim to know the intricacies of god's grand sceme, but in my mind it doesn't make sense.  If, when we die, we return to god in heaven (if good enough), that implies that we were with him before we were born, before we, as individuals, were created.  If all people are with him before they are born, and the ones who pass his test of life get to return to him, was he really giving us anything but the chance to fail his test?  If god is loving and wants people to go to heaven, then why give them the opportunity to go to hell in the first place?
