I have a testimony of the church of Jesus Christ of Latter Day Saints and that Joseph Smith was a true prophet. He restored the gospel to what it was before, before Jesus ascended. A lot of the stuff that gets thrown about is false and misinformation and has been debunked before.
Sure some of the prophets have said and their words have been treated as truth, but the prophets have not and will not ever be infallible being (neither will scripture ever be).
The Book of Mormon has often be en criticised by contain numerous anachronisms, however as time has passed the Book of Mormon has had more evidence supporting it such as many of these”anachronisms” being disproved with the existence of them being shown. For example Horses have been shown to exist pre-Columbus, writing on metal and many of the locations such as Lehi’s journey matching to maps Joseph Smith hadn’t no access too. Also with his limited education as a farm boy. He translated the Book of Mormon in about 70 days and did faster than many of our best writers in our time.
Any questions or explanations please ask and I’ll try and get back to you.
