Two videos, both produced by former Mormons. The first is a short primer on what Mormons actually believe, including God once being a mortal man from another planet who only later became God, spirit children being transported to Earth to live in human bodies, and becoming gods to rule over your own alien planets. Runs 4 minutes.
In the next video a former temple worker proposes a challenge as to what exactly will count for evidence that Mormonism is a fraud perpetrated by Joseph Smith and his successors. Runs 13:40.
