If I told you that Jesus spoke to Thomas after His crucifixion and burial, and told Thomas to put his fingers into the place where the nails were placed, what would you do next?
I would ask you if your beliefs are still as strong, when I demonstrate the repeatability of process of in-vitro synthesis of prions.
Would you still be laughing?
After that, I would show how synthetically spliced blastocysts develop into two identical twins, and then ask you if both of them will have a soul each, or just one, since your God intended the original blastocyst to develop into only one viable living being, which I just made into two.
Does God have a spare supply of souls for such instances?
