Well Terry, the word "proves" was their word not mine. However, if a child knows dates, times, places and names like this one did, going back to WWII in the Pacific, then I would say that while it is not in and of itself "proof", it certainly is "evidence". Combined with the testimonies of tens of thousands of people who have had near-death experiences and instances of "deja vu", then I would say that the entire body of evidence is "proof". But hey, that's just me, and my own personal "truth". We are each on our own journey to find it.
As for the fact that most of us can't remember past lives, that has mostly to do with our practically non-functioning pineal and pituitary glands. Actually there are many glands and it entails the entire endocrine system, but those are the main ones. This lack of memory is actually a merciful thing from our Creator, because most of us have been Barbarians at some point in the past, and we have done some horrific things. If we had full blown memory of it we would be insane.
All of our past life history is contained in that 90 percent of our DNA that science has been calling "junk". It is directly and dynamically connected to the Akashic Record, which is the history of the earth and everyone on it, indelibly stamped on the time-space continuum. It's possible that the child was psychic and tapping into that, but then I have to ask myself why he would only have the memories of one particular person.
With the New Age that's coming, children will continue to be born with an increasing amount of past life memory. They already started incarnating after the end of the Kali Yuga in 1988, and they are called "Indigo Children".
Interestingly, according to Edgar Cayce's interpretation of Revelation, during the symbolic "1000 year reign of Christ", any souls that have not sufficiently evolved into service-to-others oriented entities will not be allowed to incarnate on earth until it is over. This is what was meant by the abyssing of Satan. That means they will most likely incarnate on some other planet that's a hell of a lot worse than this one. Both the Dalai Lama and the Gnostics have said we can dissolve our egos the easier way here and now, or the harder way somewhere else after death. Oh well!
