I think there is truth in that if you believe in something it will happen.

It is scientifically proven that optimists live longer than pessimists.

I you believe you can succeed in something you are more likely to succeed in it than if you don't believe. You will never go to the lengths required to make it happen if you don't.

I don't believe miracles don't exist. I believe there could be a scientific explanation if only science had progressed to such a level as to comprehend it. But western science hasn't discovered everything - if it had we'd already be colonising other planets and we'd have the cure to all diseases.

A miracle is basically an occurence we don't understand. So naturally, once we understand the paranormal, it's not exactly paranormal anymore
