Acts of God
Almost every religion has their own accounts of miracles: divine events that seem to transcend the natural law.
But as science has marched forward, many seeming miracles wind up having scientific explanations. Still others are shown to be elaborate hoaxes.
Even so, belief in miracles continues. And despite scientific progress, there are still many miraculous phenomena that haven't been explained.
From liquefying blood to bleeding statues, here are some of the most famous and controversial miracles in history.
Apocalypse soon?Slide 2 of 21
In 1981 in the small town of Medjugorje in what is now Bosnia-Herzegovina, six children reported seeing apparitions of the Virgin Mary. For years they claimed to receive daily messages and so far have allegedly received thousands of prophecies.
"One is a prediction that there are 10 secrets that will reveal the end of the world," said Michael O'Neill, who runs the website MiracleHunter.com.
Though the Vatican has never officially weighed in, the site has attracted millions of pilgrims over the years. In 2010, the Vatican agreed to investigate this event and should have its findings out in the next few months, O'Neill said. [Doomsday: 9 Real Ways Earth Could End]Slide 3 of 21

In 1917 in the fields near Fatima, Portugal, shepherd children said the Virgin Mary appeared to them in a vision, telling them a miracle would occur on Oct. 13 that year. Thousands came to witness the event. Around Noon on a rainy day, the sun appeared to turn into a spinning disk that spiraled toward the Earth. Newspaper reporters onsite also reported the event. The church added the miracle of the sun to its list of official miracles in 1930. Some skeptics, however, point out that the effect could have been a sundog, a patch of light that appears near the sun, or note that not everyone there that day saw the miracle.Slide 5 of 21

In 1531 in the fields near Mexico City, a peasant named Juan Diego claimed to see an apparition of the Virgin Mary, who asked that a church be built in her honor. The Virgin also asked the man to gather flowers on a hillside, which he did and placed in his cloak. Afterwards, the cloak appeared to hold the imprint of the Virgin Mary. Though there have been a few scientific analyses of the so-called Our Lady of Guadalupe miracle over the years, no one has come to a definitive conclusion as to whether or how the image was painted, and if so, how it has been preserved so well.Slide 7 of 21
