@pragmatic,
pragmatic, There are supposed miracles that usually has another reason that "even" doctors are unable to explain. Doctors or scientists don't have all the answers, but that doesn't make it any more a miracle than many things man cannot still explain.
There have been studies done on prayers by the sick and their subsequent cure. Experiments have shown that prayers by third parties does not change the statistics of cures vs non-cures. What that says is that personal prayers has a benefit; it's not a "miracle."
Christians will call it a "miracle," because that's what they want to "believe."
As an unbiased observer, I see it as a benefit by the patient simply because the patient retains a positive outlook on improving their health.
There are many things we humans observe that cannot be explained by religion or science, but that doesn't mean it'll always remain a mystery. We still don't understand everything about our brains and its potential, nor is our science developed enough to understand everything about our environment. All I know is that we will learn more about our brains and our environment as time passes, and many so-called miracles will have an answer that isn't credited to a higher power.
