No, but you would agree that something sparked something entirely new around the first century, historically speaking. I don't buy into Joseph Smith's claims, but I am sure that he existed and that something came from it. I don't know if you can prove Jesus' lifetime and accomplishments outside of the bible - Not really huge on man's record of history. There are things that we know of that are recorded as history, but that are not accurate. Like the saying goes, "the winner writes the history (paraphrase)". But I believe that the bible has been protected by God so that we can read what he wants us to read.
