Is there scientific proof authenticating the Book of Mormon?

The church has made several videos available on You Tube, Yahoo, Google Video and other Internet sites. This is just one of many. I noticed that after this video finishes a person has the option to click on several other You Tube videos. There are several videos with Elder M. Russell Ballard. I noticed that several other videos not approved by the church or even favorable are also are available to view. I guess this just underscores the need for the church to get its message out because there are plenty of people and organizations willing to muddy the water.
