Catholics believe life begins at conception. Most others believe in a pre-earth life, pre-existence or a reincarnation into the current life. Martin Tanner describes the pre-existence from scripture, history and belief, from the perspectives of Judaism, Early Christianity, Catholicism, the Orthodox Church, Protestant faiths and from the Latter-day Saint perspective. Citing scriptures and examples from Near-Death Experiences, he provides compelling evidence for a pre-existence.
