Difficult Question for Mormons

Why did the angel take Nephi Plates back to heaven? Do they not belong with man? Would not their existence prove once for all that Mormonism is truth? God allowed the Jews to carry the 10 commandments for several centuries in their original physical form, written by the finger of God Himself!
How did Joseph Smith carry home the golden plates of the Book of Mormon, and how did the witnesses lift them so easily? (They weighed about 230 lbs. Gold, with a density of 19.3 weighs 1204.7 lbs. per cubic foot. The plates were 7" x 8" by about 6". See Articles of Faith, by Talmage, page 262, 34th ed.)
Why do Mormons emphasize part of the Word of Wisdom and ignore the part forbidding the eating of meat except in winter, cold or famine? (Doc. & Cov. 89:12,13).
When Christ died, did darkness cover the land for three days or for three hours? (Luke 23:44 and 3 Nephi 8:19, 23).
Joseph Smith said that there are men living on the moon who dress like Quakers and live to be nearly 1000 years old. Since he was wrong about the moon, is it safe to trust him regarding the way to Heaven? (The Young Woman's Journal, Vol. 3, pages 263-264. See reprint in Mormonism --Shadow or Reality? by Jerald and Sandra Tanner, page 4.)
Joseph Smith prepared fourteen Articles of Faith. Why has the original No. 11 been omitted? (Joseph Smith Begins His Work, Vol. 2, three pages after page 160, among the photos.)
Why did the Nauvoo House not stand forever and ever? (Doc. & Cov. 124:56-60).
Since Mormonism teaches that only God the Father had a physical body at the time Adam was created, why did God say, "Let us make man in OUR image"? Why didn't He say, "Let us make man in MY image?" (Gen. 1:26).
If Jesus was conceived as a result of a physical union between God and Mary, how was Jesus born of a virgin? (Journal of Discourses, Vol. 1, page 50).
How did Nephi with a few men on a new continent build a temple like Solomon's while Solomon needed 163,300 workmen and seven years to build his temple? (1 Kings 5:13-18 and 2 Nephi 5:15-17).
Why was Joseph Smith still preaching against polygamy in October 1843 after he got his revelation in July 1843 commanding the practice of polygamy? (Doc. & Cov. 132; and History of the Church Vol. 6, page 46, or Teachings of the Prophet, page 324).
God rejected the fig leaf aprons which Adam and Eve made (Gen. 3:21). Why do Mormons memorialize the fall by using fig leaf aprons in the secret temple ceremonies?
How do you explain the fact that 2 Nephi 16:2 is copied from an older version of the KJV of the Bible in Isa. 6:2? This is proven because this older KJV (the mistake is corrected in current versions) made a rare grammatical error by using the incorrect plural form of "seraphims" rather than "seraphim".
If the original 1830 Book of Mormon was inspired than why were there so many errors and changes and additions and deletions, when compared to current editions?
Why does the B of M use old KJV type English at a time when it was not currently used.
Why is about 1/8th of the B of M copied directly from the KJV (1611AD) when it was alleged to have been written some 1200-2000 years before the KJV existed?
How do you account for the stunning parallels in both content and order between the B of M and the View of the Hebrews, by Ethan Smith? Published in 1923 (7 years before the B of M) less than 100 miles from the Joseph Smith's parents home.
Mormon Article of Faith #8: "We Believe the Bible to be the word of God as far as it is translated correctly; we also believe the Book of Mormon to be the word of God." Why do you only add the phrase, "as far as it is translated correctly" to describe the Bible and not after the book of Mormon when in fact there are far more translating errors in the Book of Mormon than the Bible?

Did Joseph Smith really see an angel???
"Joseph Smith receiving the gold Nephi plates (the book of Mormon) from the angel Moroni." (so the story goes)...

Galatians 1:6-9, "I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed."
Colossians 2:18, "Let no man beguile you of your reward in a voluntary humility and worshipping of angels, intruding into those things which he hath not seen, vainly puffed up by his fleshly mind,"
Even if the so called angel, "Moroni", really did appear to Joseph Smith, he is still accursed because the gospel of the Book of Mormon is very different from the gospel of the Bible. Since the Book of Mormon does not conform to the standard of the Bible, it is not of Christ, but condemned being a new and false gospel.
