So the bottom line remains that my hypothesis on this matter is both scientifically and doctrinally sound.
And, tell us why your hypothesis is scientifically sound, again?
Yes, really. What scientific evidence precludes the spirit?
And
When science has irrefutable proof that the spirit doesn't exist, then my hypothesis will go against science. Until then, science accepts the possibility without assuming it's true or false.
Got it, so scientifically sound hypotheses are those for which there is no irrefutable precluding evidence. Here are just a few scientifically sound hypotheses:
1) Fairies exist.
2) Jesus drinks Captain Morgan every Sunday with Abraham.
3) Joseph Smith is the Holy Ghost.
