Just because there are two possible outcomes does not mean that they both deserve equal consideration. I could claim to be God himself. You have no real way of proving or disproving it. But if you gave it any serious consideration I would suggest that you get yourself admitted. That's how cults start. Just because two possible answers exist does not make both credible. And once again, the positive claim is the one that needs to be proved. If I claimed that I was God, it would be on me to prove it. It would not be on you to prove that I am not God, it is on me to prove it. Similarly, the God hypothesis demands evidence for any serious consideration.
