Final answer:
Jesus was first seen by Mary Magdalene after his resurrection, as detailed in the New Testament, and this event is a foundational aspect of Christian faith and teachings.
Step-by-step explanation:
At Jesus' resurrection, he was first seen by Mary Magdalene according to the Gospel of John (John 20:1-18). Early on the first day of the week, Mary Magdalene went to the tomb and saw that the stone had been removed from the entrance. After running and telling Peter and the other disciples, she returned to the tomb and encountered two angels and then Jesus himself. Matthew, Mark, and Luke also record women as the first witnesses, although there are variations in each account regarding who the women were. These accounts are integral to the Christian faith, with the resurrection being a central event that concludes the Passion of Jesus and confirms his role as the Son of God and Savior. The new religion of Christianity grew from the teachings and activities of Jesus and his apostles, greatly influenced by the recounting of resurrection experiences.
