It’s funny, because you are playing the same game that you are implying that religious people play.
You are implying that whenever an unexplainable event occurs, religious people attribute to it to God, and that this is irrational. At the same time, you are taking every unexplainable event and attributing its lack of explanation to incomplete knowledge. But this is also irrational.
It allows you to categorize truly difficult events without ever really having to examine them. When confronted by the truly difficult, you can just say that our knowledge must be incomplete. You can lump everything onto human fallibility and never have to confront events that may make you uncomfortable.
I can understand how it seems that way to you. The difference to me is that I have history backing me up. If you look back over the last 500 to 1000 years or more, you can see the progression of ‘miracles’. They used to encompass everything within the natural world from thunder and lightening or rain to more complex things like disease or diversity of life. In each case, we have figured out natural explanations to what used to be viewed as judgments from god. Now, I could look at what we cannot explain and say that it must have been due to a miracle. Or I can look back over history, notice that many things that were attributed to the supernatural actually had perfectly natural explanations, and attribute it to our lack of knowledge. In other words, you are using the ‘god of the gaps’ fallacy. Because we do not understand something at the moment, it must be god. Not a very good argument.
As an example, you dismissed the story told earlier in this thread about the baby in the ICU. You said that maybe the doctors made a mistake. Well, maybe they did, in that case. I don’t know. But there are certainly plenty of cases where no mistake was made and something genuinely unusual and perhaps supernatural happened.
So, you admit that there may be a natural explanation? Then why conclude a supernatural cause? Yes, there are many cases where people beat the odds. But as I said before, if a million people are given 10 000 to 1 odds against survival, then 100 of those will still survive. That is no more a miracle than the deaths of the rest. What about the children who did not survive? What do you say to their parents? Were they not praying to the right god? Or perhaps they prayed the rosary instead of the Divine Mercy Chaplet? Every time someone survives the improbable, it is hailed as a miracle, yet few remember the lives of those who perish.
Fatima is a great example of this. The Church investigated for an extended period of time. The finding of the Church is that the miraculous happened and that the Virgin did appear to the shepherd children. But, no Catholic is required to believe that it is true.
Perhaps that is because there is no evidence beyond the words of three children and a group of devote followers? Children are well known for embellishing the truth at times, and people can see what they want to see, especially when there are inconsistencies in their reports. Mob mentality and the power of suggestion are quite powerful and staring at the sun is not so good for your eyesight

. So I have a difficult time believing that the claims for miracles are as carefully scrutinized as you claim. Now, I do know that the Catholic church does dismiss many perceived miracles, normally the ones where there is solid evidence for a hoax. However, it is impossible to prove or disprove visions.
I am confused though. If there really was solid evidence for this miracle, then why are Catholics not required to believe in it?
Do you have a list of miracles that have been accepted in recent years? I searched for a few minutes and did not find anything. It would be interesting to see how many miracles on that list are things like apparitions and how many are cures from disease or something in which there is solid evidence of a problem prior to the miracle.
That said, the existence of miracles is an interesting problem to me. I have always thought that faith was important in the belief in a god. As far as I remember, the bible will back me up on that one, and perhaps Ahimsa will too

. So, if miracles do indeed exist and prove the existance of the supernatural, then what is the use of faith? In fact, does that not negate the need for faith? And what about all the miracles that believers in other religions experience? Does that mean that god is not simply Christian or Muslim or Hindu? Would a generic theistic god be a better explanation of the observance of miracles in all religions?
