Mangasar Magurditch Mangasarian (1859-1943) was an American atheist. His most popular books deal with the evidence against the existence of an historical Jesus. The majority of his writing covers topics on religious criticism and the philosophy of religion. The arguments presented in section one of The Truth about Jesus: Is He a Myth? show that there is no factual evidence for the existence of Jesus. This is a hard concept to grasp since we have been taught since childhood that he was an actual man living in the first century.
