The everyday, average, human being, knows little to nothing, about how the human brain works. Most people, outside of neuroscientists, brain surgeons, psychiatrists, and psychologists, know nothing of what is really going on inside their heads. Most people are not aware of the fact that our brains can, and do, at times deceive us. Even completely sane and rational people sometimes see, hear, or even smell things that are not really there.
Our eyes, for example, do not take in everything we think we see in the world around us. If they did we would experience sensory overload. We only see the things that our brain deems relevant. Have you ever done a double take ? Have you ever been fooled by an illusionist ? Also, because of the way humans evolved, we are pattern seekers. It helped us to survive. It was better for us to see what we thought was a large predator and be wrong than to see an actual predator but mistake it for something else, or we wouldn't be here today. Anyone can look up at the clouds and soon begin to see familiar shapes in them. Some people can see what appears to be faces in particular combinations of shadow and shape in tree foliage, or in any number of other things. We continually and unconsciously search for patterns everywhere.
Sometimes people catch a fleeting odor of smoke when there is nothing burning, or maybe a fleeting smell of brownies baking. This has happened to us all at times. Sometimes our ears plays tricks on us. We might hear our name being called by our mother or father, or someone else familiar to us, only to find out when we ask them if they called us that they hadn't.
What does all this have to do with to do with statistics and miracles ? Simply this: There are seven billion people on earth. That is an unimaginably large number of people. Considering that many people, it would be strange if nothing seemingly unexplainable ever happened just by mere chance, plain old coincidence, something that might be deemed a miracle by the person who experienced it, even though no god were really responsible for it.
According to Guy P. Harrison, award winning journalist and author of several books on beliefs people hold, if only one person out of a million experienced some unexplainable event every day, then strange, seemingly miraculous things would occur seven thousand times every day, and two million, five hundred, and fifty-five thousand times every year in a world of seven billion people, and all by mere chance with no divine intervention. And if these seeming miracles happened by mere chance to one person in a billion every day, then these strange events would happen to someone in the world seven times every day, and two thousand, five hundred, and fifty-five every year, no god required.
These seeming miracles would also include seemingly prophetic dreams that happened to correctly portend future events. After all, every person dreams thousands of dreams over the course of a lifetime, and there are seven billion of us dreaming. It would be strange if out of all those dreams, even if there were no God, if no one's dreams just coincidentally happened to predict some future event. The same is also true of prayer. It would be strange, even if there is no God, if out of seven billion people, no prayers ever coincidentally seemed to be answered.
