You seem to be presuming that God caused the deception in the hypothesis. No religion has all the answers, and it seems that all of them contain such fuel for idiots to hang onto and use to abuse others. But religion is very much part of the human condition. As Kirsten does in all of her e-mails, she inspires me to think here. Thank you, Kirsten.
Religion is made by man, for man.
Or, I should say, for certain men. If God were to appear to me and say the Bible was false, Yes, I would most definitely believe in God. God is not constrained, contained or constricted into any man-made document, whether it suits your soul to call it inspired or not. The Druids believed that whatever was required for you at that point on your path was required for you. Icons, statues, Bibles, whatever.
