By the time Lehi and his ragtag band of wonderers made it to the coast, they had worn themselves out by subsisting off the land for 8 years by living in the wild and even eating raw flesh because they couldn't always cook it. They eventually made it to the coast and there would build a ship. They built a ship on their own. They built it of their own accord and of their own materials and of their own labor. NOTHING is said of outside assistance! They did not construct a ship after the manner of men but in their solitude depended on God to show them how to build it. They were truly alone on the coast in which they founded and named for themselves: BOUNTIFUL,"we called the place Bountiful, because of its much fruit."
The narrative of the Book of Mormon let's us know that Lehi and his family were truly alone and did not depend on the arm of flesh to aid them because they had the Lord in all things.
They sojourned for 8 years on their own with only the help of God:
1 Nephi 17 wrote:4 And we did sojourn for the space of many years, yea, even eight years in the wilderness.
God prepared Bountiful in which *THEY*
named the land in order to preserve their lives on the seashore and aid them in building Nephi's ship. They were alone and depended entirely on the Lord for all things to include divine instructions on how to construct a ship not built after the manner of men. They were alone on the coast just as they had been alone in the wilderness!
1 Nephi 17 wrote:5 And we did come to the land which we called Bountiful, because of its much fruit and also wild honey; and all these things were prepared of the Lord that we might not perish. And we beheld the sea, which we called Irreantum, which, being interpreted, is many waters.
Lehi's party was all alone on the coast. There was no civilization or people to aid them. There was nobody except them. Nephi goes up to a mountain to pray about what to do. He doesn't know where to turn.
1 Nephi 17 wrote:9 And I said: Lord, whither shall I go that I may find ore to molten, that I may make tools to construct the ship after the manner which thou hast shown unto me?
Ship construction was performed under management of God only. There were no other souls to assist them as they built the ship in their own way.
1 Nephi 18 wrote:1 And it came to pass that they did worship the Lord, and did go forth with me; and we did work timbers of curious workmanship. And the Lord did show me from time to time after what manner I should work the timbers of the ship.
2 Now I, Nephi, did not work the timbers after the manner which was learned by men, neither did I build the ship after the manner of men; but I did build it after the manner which the Lord had shown unto me; wherefore, it was not after the manner of men.
Finally, they being alone apart from civilization being separated from all other people they launched the ship all by their lonesome selves.
1 Nephi 18 wrote:4 And it came to pass that after I had finished the ship, according to the word of the Lord, my brethren beheld that it was good, and that the workmanship thereof was exceedingly fine; wherefore, they did humble themselves again before the Lord.
5 And it came to pass that the voice of the Lord came unto my father, that we should arise and go down into the ship.
6 And it came to pass that on the morrow, after we had prepared all things, much fruits and meat from the wilderness, and honey in abundance, and provisions according to that which the Lord had commanded us, we did go down into the ship, with all our loading and our seeds, and whatsoever thing we had brought with us, every one according to his age; wherefore, we did all go down into the ship, with our wives and our children.
There was no seaport and no outside assistance for Lehi and his family. They were alone. They built the ship not after the manner of man and neither did man aid them or assist them in launching the ship. There is no account of any outside assistance other than that of the Lord showing them what to do. Any inference that man assisted Nephi is the apologetic imagination attempting to make sense of a story that makes no sense.
1 Nephi 18 wrote:8 And it came to pass after we had all gone down into the ship, and had taken with us our provisions and things which had been commanded us, we did put forth into the sea and were driven forth before the wind towards the promised land.
I bear testimony that the Book of Mormon is pure fiction.
