Suppose he just gave me the money.. would that miracle alone be considered an act of God?

If you insist on the rules of evidence that are used in a criminal court proceeding, that is, "beyond the shadow of a doubt," then, no, the existence of God cannot be proven. However the existence of God can be inferred by a "preponderance of evidence" as required in a cvil court proceeding. Consider for a moment that which we do know and is generally accepted as true: We know that the universe, of which we are a part, came into existence some 13.7 billion years ago in a blinding flash of radiant energy known as "the big bang." (The phrase was coined by British astronomer Fred Hoyle.) The universe then bore no resemblance to what we behold today. There were no stars, no planets, no galaxies, no people to ponder these things...There were not even atoms!! Eventually the radiant energy condensed into sub-atomic particles which became the building blocks of everything we see today. These facts beget a question: Given 13.7 billion years of time, can a mindless jumble of chaotic sub-atomic particles rearrange themselves into people and brains without there being any thought or guiding intelligence behind it?? The correct answer is, yes, it is possible. But is it probable?....No. Considering all the scientific research being done into matters like near death experiences, electronic voice phenomena, spiritism, mediumship, etc.......all pointing to the existence of a non-physical realm, the argument for a creative force and intelligence behind it all, takes on added momentum. As for James Randi, his offer is bogus. He is a closed-minded skeptic who has said, "I'll always have a way out."

Actually, you don't even have to go that far, just do any of the following: "At JREF, we offer a one-million-dollar prize to anyone who can show, under proper observing conditions, evidence of any paranormal, supernatural, or occult power or event." See the link to his site: http://www.randi.org/site/index.php/1m-challenge.html Of course the gullible will claim that the offer is bogus and Randi a fake--but that's the only ammo they have against logic and facts. +4 for the question.
