For the shirtless man,(you gotta love a guy who has the guts to post himself shirtless). Bravo!
I am glad that you brought up all those points. Most mormons have not done their homework the way I have. Most don't really have to because, like you said, faith in Christ and good principles are the only thing you really need.

However, I find it fun to dig

for the truth and mysteries of God. I am grateful to be able to answer your questions because I believe I can do so in a satisfactory manner.
Point number 1: Yes we do believe that many tribes have some bloodline of descendency from people of Israel. But it is not that simple. Herein lies the misconception that even a lot of Mormons hold because they are not as studious of the Book of Mormon as they should be. There were three main migrations spoken of in the Book of Mormon. The nation of Lehites which divided into 2 peoples of the same blood called Nephites and Lamanites. The second people spoken of but often forgotten were the Jaredites. The third, often glossed over completely are the Mulekites. I can delve into each of their histories in detail later if you like, but to sum up. The first people here, the Jaredites actually came from Asiatic area of Babylon. Quite a different DNA scheme. They were the first ever to set foot on this continent. This people as a nation dissolved and spread into unknown parts of the continent, certainly later mixing in with the future nations that would come, first mixing with the Mulekite people, who also came from the land of Jerusalem about 12 years after the more famous Nephites and Lamanites.
I can't remember

exactly the study, but I can produce it later if need be that showed that the people of the Americas were found to be primarily descended from Asiatic origins, which would fit perfectly in with the chronology of the Book of Mormon.......whew!
Oh yes, point two, the "Nuclear submarines" in question. The vessels themselves had to be made differently than your normal ship of the day with it's sails and common boat shape. To be clear, the people who first used these vessels were the Jaredites when they were told by God to take up this voyage. To a westerner, I agree, this story does not make much sense

. But when put into historical context, it is an impressive stamp on the authenticity of the book.
First it has been well documented that most of what we have learned of Ancient weather and dates of storms and destruction has been discovered in the last 100 years with the carbon dating process and knowledge of Geology and so on. We have learned in this time that there was a great and terrible weather pattern which leveled entire civilizations and left thriving cities, such as Bablyon completely destitute circa 2200 bc,

right around the time the jaredites left bablyon. Strikingly, The most learned scientists of 1830 had no such knowledge of this timeline of destruction. Certainly not a poor farmboy named Joseph Smith in upstate rural New York.

Hence had these Jaredites been in regular ships with sails, it would have been a quick destruction for all on board. The construction of the ships was very peculiar, not like a submarine like you have described, but certainly "tight, like unto a dish" as Ether points out. "Ye shall put a hole in the top thereof, that will close tight like unto a dish so that when the mountain waves shall dash upon you, you shall not be broken into pieces. You shall be as a whale in the sea, and I shall cause my winds to blow and a tempest to be thy wind continually blowing toward the promised land." I know I slightly misquoted the scripture in Ether because I don't have my book with me, but those are basically the words spoken to "the brother of Jared" in the book. "And when ye shall suffer for air ye shall unstop the hole when you come to the surface".
They were not submarines. They were boats that would normally float on the water, but because of their shape, could stand for short whiles to be underneath water for a time. Just like a whale that needs to come up for air......whew...
Next point... where was I?
Oh yes, the great cities and their locations. We all know that there have been cities that have been buried by volcanic eruptions, or erased by large earthquakes and floods and such throughout the ages. Then why not in America. But some may say, well certainly not all the cities would be lost right? It would take one heck of a natural disaster wouldn't it? Yes it would.
The book of mormon talks about just such a disaster, where after the death of Christ, Mountains were removed out of their place and fell on cities, giant waves, tornadoes and and vicious earthquakes that lasted for the space of three hours. Do any of us have any idea what would happen if a magnitude 9 earthquake shook for three hours? We do if we look in the book of mormon. Think something like that couldn't happen? Just watch that show on TLC Mega Disasters.
