Yea, you anti's post what specific reason you think that the witnesses should not be believed, not only the eleven, but the others also!
Regarding the Kinderhook plates, it's not too difficult to get a group of people to "witness" something:http://mormonthink.com/kinderhookweb.htm
We, the citizens of Kinderhook, whose names are annexed, do certify and declare that on the 23rd of April, 1843, while excavating a large mound in this vicinity, Mr. R. Wiley took from said mound six brass plates of a bell shape, covered with ancient characters. Said plates were very much oxydated. The bands and rings on said plates mouldered into dust on a slight pressure. ROBERT WILEY, W. LONGNECKER, GEO. DECKENSON, FAYETTE GRUBB, W. FUGATE, W. P. HARRIS, J. R. SHARP, G. W. F. WARD, IRA S. CURTIS, (From the Quincy Whig.)
Regarding the witnesses to the supposed golden plates, I think David Whitmer was very clear:http://mormonthink.com/witnessesweb.htm
David Whitmer said "If you believe my testimony to the Book of Mormon; if you believe that God spake to us three witnesses by his own voice, then I tell you that in June, 1838, God spake to me again by his own voice from the heavens, and told me to separate myself from among the Latter-day Saints, for as they sought to do unto me, so should it be done unto them."
And then we have the Soloman Spalding "witnesses" http://mormonthink.com/witnessesweb.htm
SOLOMON SPALDING WITNESSES
There are seven witnesses that say Solomon Spalding was the author of the Book of Mormon. Seven people wrote affidavits testifying that they had read early drafts of the Book of Mormon by author Solomon Spalding. In some ways they are more credible than the Book of Mormon witnesses as they each wrote their own account instead of merely signing a prepared statement.
Here's the testimony of the first of these seven witnesses, the brother of Solomon Spalding:
He [Solomon] then told me had he been writing a book, which he intended to have printed, the avails of which he thought would enable him to pay all his debts. The book was entitled the "Manuscript Found," of which he read to me many passages. -- It was a historical romance of the first settlers of America, endeavoring to show that the American Indians are the descendants of the Jews, or the lost tribes. It gave a detailed account of their journey from Jerusalem, by land and sea, till they arrived in America, under the command of NEPHI AND LEHI. They afterwards had quarrels and contentions, and separated into two distinct nations, one of which he denominated Nephites and the other Lamanites. Cruel and bloody wars ensued, in which great multitudes were slain. They buried their dead in large heaps, which caused the mounds so common in this country. Their arts, sciences and civilization were brought into view, in order to account for all the curious antiquities, found in various  parts of North and South America. I have recently read the Book of Mormon, and to my great surprize I find nearly the same historical matter, names, &c. as they were in my brother's writings. I well remember that he wrote in the old style, and commenced about every sentence with "and it came to pass," or "now it came to pass," the same as in the Book of Mormon, and according to the best of my recollection and belief, it is the same as my brother Solomon wrote, with the exception of the religious matter. -- By what means it has fallen into the hands of Joseph Smith, Jr. I am unable to determine.
