The history of the Mormon church provides an interesting test case for many of the arguments that Christian apologists make.
If Jesus hadn’t actually been raised from the dead, the Romans or the Jews would have produced his body and that would have nipped Christianity in the bud.
There has never been any shortage of people to point out the absurdity of the Joseph Smith’s claim that the American Indians are descended from tribes of Israelites who migrated to the New World hundreds of years prior to the birth of Christ. Nevertheless, there has never been any shortage of Mormons who would happily dismiss such criticisms as deceptions of the devil. The notion that religious enthusiasms are subject to logical refutation is not supported by the evidence.
The rapid spread of Christianity couldn't have happened if it's historical claims had simply been invented.
It has taken less than two centuries for Mormonism to grow to almost 14,000,000 adherents. Although we do not have accurate figures for Christianity's growth its first 200 years, it is hard to believe that Mormonism compares unfavorably.
Nobody knowingly dies for a lie. Early Christians would not have willingly endured persecution if the resurrection was a hoax.
Early Mormons followed Joseph Smith from New York to Ohio to Missouri. In Missouri, the governor called out the militia to exterminate the Mormons or drive them from the state. Vigilantes killed many Mormons and the Mormons moved to Navoo, Illinois where Smith was arrested and lynched. Nevertheless, many Mormons willingly endured great hardships to follow Brigham Young. If willingness to endure hardship and risk persecution is proof of a religion's claims, then it is reasonable to believe that the Garden of Eden really was somewhere in Missouri.
We have no record of any of Christianity's early critics disputing that Jesus was a real person or that his tomb was empty.
If we only had the records preserved by the Mormons, we would have a much different picture of the Church's history than we have today. For example, when the Mormons slaughtered 120 settlers in the Mountain Meadows Massacre in 1857, the official LDS position was that the Paiute Indians were responsible. If not for independent investigations establishing Mormon responsibility, the church would have continued to deny it. If we only had Mormon sources, we would believe that the LDS had abandoned polygamy completely in 1890 when in fact its leaders continued to take multiple wives for many years thereafter. Since the earliest records of Christianity are the ones that the Catholic Church chose to preserve, we cannot take much comfort from the fact that we lack records of people who challenged orthodox beliefs.
