Craig Keener has written a two-volume set (
http://bakerpublishinggroup.com/books/miracles/335370) studying both the New Testament and current day miracles. You may want to check that out if you're serious and not just trolling. There's also a 45-minute youtube (
https://www.youtube.com/watch?v=rn73J9A0SnU) of him presenting his research, if you want to sit for that long.
The problem with what you want is that it would take the effort to set up the experiment, agree on methodology, establish a control set, and be able to regular all possible factors to be able to truly determine whether a true miracle verifiably happened. This simply isn't the way God works. Realistically, that means that a person with miracle ability contacts a research organization to find funding, set up the parameters, establish the rules, regulate the control group—and then say, "OK, NOW do your miracle." Say what? That's not how it works.
Then suppose the miracle worker heals a person. Who's to say that somebody isn't going to say, "Well, that would have maybe happened anyway. Maybe their body just did it and the timing was lucky." It's not trying to be smart aleck, but just wondering how you're ever going to get what you're asking.
Let me give you a real life example. My son, at 19 years old, was suddenly rushed to the hospital with a life-threatening stroke. It was a Sunday evening, he was totally incoherent, and his one side was non-functional. When he talked it was total babel. The doctors said he may not live, and if he did, his functionality might be minimal. His church gathered to pray, and by email and Facebook, people all over the world also prayed. The next morning the church had a special prayer meeting at 6 in the morning. My wife and I went into his room at 9 am on Monday morning. He said to us (I kid you not), "Hi Mom. Hi Dad. What's going on?" I was THERE. I consider this to be miraculous. Later diagnoses identified that the stroke was in his brain stem, where life functions reside. And yet the very next morning, after the prayers of many, he was talking coherently, and today lives a productive life.
I told this story once before once on this forum. Here's the reaction I got: "Yeah, that's not a miracle, dude. Be serious. That's a dude recovering from a stroke like lots and lots of other people do all the time. Be thankful to the medical staff. They're the ones who saved your son."
So who's to ever be able to document miracles in a conclusive way? How would you even do that?
