Your claims are unsubstantiated. They cannot be tested and to say the least, they are hearsay. If you claim to do miracles then in a way, you are immortal. You could try to slit your throat and then try to heal yourself but I am not sure it will roll out well for you.

Next, everyone with a serious intent to investigate and I shall use Christianity as the example as I know the most about it knows that the persecution of Christians wiped out most of any facts or formulas.

You cannot know, unknown unknowns. How do you know the formulas that have been wiped out, if they had indeed been wiped out? You are caught up here in your own logical fallacy.

Jesus is not his name, for example. Well, if that not his name can we expect the best results when it is used? This is indeed a problem. As for what his name actually is or if by now if he really cares if it is used correctly? That I leave for your investigation.

Sure. Jesus was not his name. It was "Christus" which means "the anointed one". It was a title more used from people that were teachers. Nonetheless, there is no evidence for Christus to have ever existed. Rather, what exists, is a conglomerate of different stories, from different people, all making up one identify - Jesus. This is how myths are constructed and we have plenty of evidence for that.

Thank you for your detailed comment.
