I watched the entire video on youtube.
at about 3:17, the presenter says words to the effect that parts of each of Joseph's descriptions of the facsimiles don't match up with Egyptologists say is in the pictures.
Here is the interesting thing. Even though a man is called an Egyptologist, it does not mean he knows all there is about ancient Egypt. In fact, I'm guessing he knows less than 10% of everything ancient Egypt.
So if an Egyptologist says "per our knowledge, I think JS does not translate this correctly", you have to take into account the 10% problem. No Egyptian or Egyptologist knows the special nuances and deep secrets of the thoughts of the men that created the figures and symbols that are presented in their writings and drawings in their tombs and temples.
What we have to do is look at each figure or symbol individually on the facsimile, that JS said something about. JS hit many of these figures or symbols right on target, as to how the Egyptologist would have agreed. How could JS hit anything ancient Egyptian right on target? Did he have a book or information from the doctors or scientists of ancient Egyptian origins. Not in Nauvoo, Illinois, the frontier jumping off point to the wild west territories, in the 1830's, and having no access to anything ancient Egyptian.
So what about those things he got wrong. Wrong by who's word? An Egyptologist? You know that if you give 10 Egyptologists a piece of writing in ancient Egyptian, and ask them to translate the writing, you would get 10 different translations. So what about those thing that do not agree with Egyptologists? Are they really wrong? No, they are wrong according to the knowledge of the Egyptologist (10% problem), but not wrong period. They look wrong according to our knowledge today, but what happens if in 20 years we find out that what JS said was right on target.
It is like the translation of the BOM. When JS published the BOM, scientists howled and laughed with glee that this stupid JS would write such things about ancient American people that were scientifically so wrong, according to the knowledge of the scientific community, who are experts in ancient American history. Some 30 items that were perposterously stupid, JS should be embarrassed.
But 150 years later, of those 30 items, 23 of them have been proven to be scientifically true, 2 are on the verge of being proven true, and 5 are still not proven one way or the other. (this is an example, the numbers could be different, but the point is taken).
The BOA facsimilies are in the same state of criticism.
why would God inspire Abraham to write a book and then leave it hidden for maybe 3,500 years?
Why would God inspire Enoch to write a book and then leave it hidden for maybe 4500 years?
Why would God tell us in the Bible to read the epistle to the Laodiceans (Revelation 4:16)
and then allowed the book to go out of existence? Have you ever read this book?
Why did God allow Noah's writings to go out of existence?
Why did God not allow us to read many of the NT writers?
I could go on, but I hope this makes sense to you. We do not know why God did these things.
We must have faith that what we have and what the present prophets and apostles are telling us is enough to get us to the kingdom of God.
