If you are an antichrist, you won't believe in the bible prophecy from the beginning. Which means, you won't believe that physical immortality will become possible.
I think even if I did the research mentioned above, it would be a total waste of money because if those people don't believe in the testimonials, they won't believe in the research at all. They would say that I made it all up. So why waste money?
Testimonials are enough to convince people for now.
