So now that this thread is rightly in R&P then why not call his bluff and agree with him. Let him paint himself into a corner.
I have tried. I've asked him if there are more people today than ever before on Earth (which is historic fact), where do the extra "selves" come from? If these extra selves are created de novo according to his theory, why are any selves reincarnated (recycled)? Doesn't this invalidate his proof of reincarnation? If both do happen, however hard to prove, then are some of us reincarnated and others freshly made? Can one tell the two apart?
So far, silence on his part.
