The evidence of the paranormal is another story, and though related, that's not the argument here. As is bringing in Santa Claus and the Tooth Fairy, because it's common sense that they don't exist. Whether they did exist in some form, at one time in the past, is another matter entirely, of course.
Darthphere, that's what I mean about someone making a comment that parents wanted to use their child's imagination to make money. I was being facetious; you made it sound like the parents told the kid to tell them specifics so they thought it a good idea to make some $, when it's also common sense no tangible evidence has ever existed.
However first hand accounts of reincarnation have persisted, as does in religion such as Buddhism.
