"If you wish to upset the law that all crows are black, you must not seek to show that no crows are: it is enough to prove one single crow to be white. My white crow is Leonora Piper."

As with The Zepro Formula, probability theory can be used to provide a mathematical proof for the existence of an afterlife: all that's necessary is to prove the authenticity of just one of the millions of ghosts, cases of reincarnation, or Electronic Voice Phenomena or Near Death Experiences---it's that simple.

1. The Whaley House, San Diego, California. Compared to many ghosts that are associated with a tragedy during their lives, or a violent death, the history of The Whaley House involves only the California pioneer Tom Whaley, his wife and some relatives who led relatively ordinary lives and died the same way.
   However, since The Whaley House was declared a historical museum, thousands of visitors visit it each year--and many of them have witnessed ghostly members of the Whaley family wandering about the premises. In fact, these ghosts have been seen and even photographed by so many people that The Whaley House is not only considered the most haunted house in America, it's listed by the United States Department of Commerce as an authentic haunted house!
   
   
2. The San Antonio Railroad Track Ghosts. This phenomenon has become so well known that it's become a popular tourist attraction--much like The Whaley House in San Diego, and several years ago The Discovery Channel aired a documentary on the subject.
   On a spot just outside San Antonio, Texas, there's a dirt road that crosses some railroad tracks. The urban legend is that a long time ago--no one knows exactly when--some children were killed when a freight train ran into their school bus...
   There's only one problem with this story. There's absolutely no record of any such accident, even though public records go back to the 1850's.
   But the story gets even stranger: Many of the streets in the area are still named after the children who supposedly died in the accident!
   These San Antonio ghosts don't seem to be bothered much by the facts, however, because to this day if you drive down this road and stop your car a few hundred feet away from the tracks, put it in neutral and stop the engine, something extremely strange will happen: your car will start to move--right toward the tracks! This is extremely unusual for the simple reason that the road goes uphill to the tracks--and your car will continue to move straight over the tracks, and then come to a dead stop.
   The legend is that the spirits of the dead children still haunt this road and will push your car over the railroad tracks to prevent the same horrible accident that killed them--even though there's no record at all that any such accident happened in the first place.
   This bizarre event been witnessed by so many people that tourists and even school teachers bring their students to these railroad tracks, sprinkle talcum powder on the back of their cars, and then get back inside to be pushed uphill across the railroad tracks. When they get out again and walk to the back of the car, they always see tiny children's handprints on the talcum powder!
   The film crew for The Discovery Channel documentary contacted Roy Williams, a retired commander of the Texas Highway Patrol, to either confirm or deny this story by thoroughly wiping off and then sprinkling talcum powder over the back of his car. The camera followed him across the tracks, and then recorded him getting out of his car and walking to the back of his car to check for prints... Even this hardnosed, cynical cop had to smile when he saw the children's fingerprints in the talcum powder.
   
   
3. The Murder of Teresita Basa. On February 21, 1977, a woman by the name of Teresita Basa was found brutally murdered and partially burned in her Chicago high-rise apartment...
   There were no clues and no suspects.
   Dr. Jose Chua and his wife worked at the same hospital as Teresita, but they barely knew her. Nevertheless, one evening Mrs. Chua suddenly went into a trance and announced in perfectly fluent Tagalog, a Phillipine dialect--
   "I am Teresita Basa."
   She then proceeded to tell the Chuas that she was murdered by an orderly, Allen Showery, who had stolen her jewelry and given her pearl cocktail ring to his wife...
   Terrified, the Chuas reported the information to the Chicago police. Two veteran detectives assigned to the case were highly skeptical of the information, but having no other leads, they decided to investigate. When they searched Showery's apartment, they found Teresita's jewels--and his wife had the pearl cocktail ring!
   When Allen Showery was confronted with this evidence he immediately confessed to the murder of Teresita Basa, but at trial his attorney moved to dismiss the case on the grounds that evidence provided by a ghost is inadmissible in a court of law.
   The judge disagreed. Allen Showery was convicted of murder and sent to prison for fourteen years...
   The decision created quite a stir in legal circles because it was the first case on record in which the chief witness for the prosecution was a ghost.
   
   

1. Xenoglossy. This bizarre phenomenon is defined as the sudden ability that someone has to speak a foreign language that the person never learned. There are many documented cases of xenoglossy, and one such famous case involves a Canadian child psychologist who was hypnotized and started speaking a language that was dead for so long that experts had to be called in to understand what he was talking about.
   Another classic case is Uttara Huddar, the woman who actually spoke a language she'd never heard while she was wide awake--plus the fact that she gave dozens of exact details of her former life that were all proven to be accurate!
   
   
2. Shanti Devi. Very often children are born with memories of past lives. The case of Shanti Devi, who was born in India in 1926, was investigated by a special committee of prominent professionals appointed by Mahatma Gandhi himself, and her life stands as one of the most famous, thoroughly documented cases of reincarnation on record...
   Almost two years after an Indian wife named Lugdi died in childbirth, Shanti Devi was born in a village near Delhi. Around the age of four, Shanti Devi began to speak of herself as a woman named Lugdi who lived with her husband and several children in the village of Mathura. The child spoke in great detail about her past life, from the house she lived in to the food she ate. As the years passed, Shanti insisted on visiting Mathura and seeing her husband and children.
   Concerned, her parents finally relented and took her to Mathura, where she correctly led the way to the house where she claimed she lived. In an attempt to trick the child, one of her escorts introduced to her a man he identified as her husband's brother. Shanti Devi immediately blushed and said, "No, he is not my husband's brother. He is my husband--didn't I tell you that he is fair and has a wart on the left side of his cheek near his ear?" She then proceeded to describe details of her former life that only Lugdi and her husband could have possibly known, down to the well in the courtyard of their house where she used to bathe.
   Word of Shanti Devi's amazing visit to Mathura immediately spread throughout India and the incident created such a stir that Mahatma Gandhi appointed a committee of fifteen prominent professionals, including parliamentarians and members of the media to investigate the case...
   On November 24, 1935, this committee, along with Shanti Devi and her parents again visited Mathura where the child not only correctly described all the changes in the town that had taken place since Lugdi died, but she also led her escorts to the spot where she claimed she used to bath in a well. There was no well, but when someone removed a stone where the child was pointing, a well was discovered underneath...
   When Shanti Devi met the parents of her former life, she burst into tears, and she also described in great detail to Lugdi's husband, Kedarnath, the exact manner in which they had made love in her former life as Lugdi..
   . Later Shati Devi admitted to a physician, "Yes, that is what fully convinced him."
   Even after the case of Shanti Devi had been confirmed by Gandhi's special committee, for years afterward she was investigated by hundreds of critics, prominent public figures and researchers from all over the world....
   One critic who had traveled thousands of miles to expose the child as a fake finally concluded after his investigation: "This is the only fully explained and proven case of reincarnation there has been.
   Dr. Ian Stevenson disagreed. He had studied many, many children exactly like Shanti Devi...
   
   
3. The Case Studies of Dr. Ian Stevenson. For the last forty years Dr. Ian Stevenson has meticulously documented over 3,000 cases of children who have been reincarnated. As one of the first major scientific researchers in this field, Dr. Stevenson has published numerous studies, the most famous of which is his 1974 book, Twenty Cases Suggestive of Reincarnation. The most convincing evidence includes children who have been photographed with birthmarks that coincide exactly with autopsy wounds of the murdered adults that these children had been in previous lives.
