That's a matter of faith, not fact. There is no empirical proof. I'm not saying it didn't happen, but there is no way to prove it, and anyway proving it is not the point. I think its a futile exercise to "prove" the existance of God. If you have faith, everything around us is proof. If you are not a believer, nothing will convince you. I respect the belief, but saying something doesn't make it so. If you believe it, be happy with that. Why bother to "prove" it to people. Its either self-evident or not. Some crackpot code would be the last thing to convince anyone.
sorry, but my opinion this crap is all to sell books to the gullible. Its meaningless.
