You are mistaken. In fact, to put it bluntly, that's a blatant lie. The existence of the Afterlife has never been "disproved", for obvious reasons, just as the existence of God has never been disproved and the existence of little green men on Alpha Centauri X1 has never been disproved.past life crap has been disproved many times
You may not care to accept the evidence - and that's fine - but please don't lie about it. Especially if you haven't even read it.
