Is the Book of Mormon, like the Bible, written by the hand of God through men, or is it only just invention of a man who deceived his flock? One only has to open the Book of Mormon and read it to find that the gross inaccuracies contained in the book show that this is not the word of God at all, and that Joseph Smith DID deceive his followers by writing fiction.
1) I Nephi 18:21 And it came to pass after they had loosed me, behold, I took the compass, and it did work whither I desired it. And it came to pass that I prayed unto the Lord; and after I had prayed the winds did cease, and the storm did cease, and there was a great calm.
-The compass was not even invented until 1800 years later.
2) I Nephi 8:25 And it came to pass that we did find upon the land of promise, as we journeyed in the wilderness, that there were beasts in the forests of every kind, both the cow and the ox, and the a$$ and the horse, and the goat and the wild goat, and all manner of wild animals, which were for the use of men. And we did find all manner of ore, both of gold, and of silver, and of copper.
-Cows and horses did not exist in the Americas at that time, and would not exist until 2000 years later, when Europeans brought them over.
I Nephi 4:9 And I beheld his sword, and I drew it forth from the sheath thereof; and the hilt thereof was of pure gold, and the workmanship thereof was exceedingly fine, and I saw that the blade thereof was of the most precious steel.
-Steel did not exist in the Americas until Columbus.
Enos 1:20 And I bear record that the people of Nephi did seek diligently to restore the Lamanites unto the true faith in God. But our labors were vain; their hatred was fixed, and they were led by their evil nature that they became wild, and ferocious, and a bloodthirsty people, full of idolatry and filthiness; feeding upon beasts of prey; dwelling in tents, and wandering about in the wilderness with a short skin girdle about their loins and their heads shaven; and their skill was in the bow, and in the cimeter, and the ax. And many of them did eat nothing save it was raw meat; and they were continually seeking to destroy us.
-The cimter is a curved sword, with the sharp edge on the convex side. None have ever been found by archaeologists studying the Americas.
Mosiah 7:22 And all this he did, for the sole purpose of bringing this people into subjection or into bondage. And behold, we at this time do pay tribute to the king of the Lamanites, to the amount of one half of our corn, and our barley, and even all our grain of every kind, and one half of the increase of our flocks and our herds; and even one half of all we have or possess the king of the Lamanites doth exact of us, or our lives.
-Barley did not exist in the Americas at that time.
Ether 2:3 And they did also carry with them deseret, which, by interpretation, is a honey bee; and thus they did carry with them swarms of bees, and all manner of that which was upon the face of the land, seeds of every kind.
-Honeybees did not exist in the New World until Europeans introduced them in the 1700's.
