Hello. I'd like to ask about proof of miracles and of God -- and, in particular, what the standard of proof is. Arthur C Clarke said something like, "Any sufficiently advanced technology is indistinguishable from magic." Well, if a voice booms down from the heavens, tells you that it's God, parts the Red Sea and gives prophecies that come true, are there no other explanations for these events except "miracles", and would the unusualness of these events be strong enough to establish that the voice in fact is God?
