What I meant was that you defined ‘miracle’ wrong.  A miracle is an effect without a cause (in the physical universe, God being outside of such things for some reason).  Of course, such things don’t really exist.  There are just some causes that haven’t been worked out yet.

While I do understand what you are trying to say.  I wonder what you call it when someone is told they are dying and then suddenly they recover.

It happens all the time.  Humans are A) not infallible, and B) not omnicient.  Just because a person recovers from a seemingly terminal illness or injury doesn’t mean that a miracle happened.  It just means that either the doctors missed something (a not uncommon occurrance) or that the person beat the odds and survived.  Even a 1 in 1,000,000 chance occurs every now and then.  If it didn’t, then that would be miraculous.
