Step-by-step explanation:
The two religions I have chosen are Islam and Christianity.
Islam:
Islam originated in the 7th century CE in the Arabian Peninsula with the life of Muhammad the Prophet. Muhammad is considered the last and final prophet in Islam. The catalyst for the birth of Islam was Muhammad's revelation from God, which is documented in the holy book of Islam, the Quran. Muhammad's teachings and the spread of Islam were instrumental in shaping the history and culture of the Middle East and beyond.
Christianity:
Christianity can be traced back to the 1st century CE in Palestine, with the life of Jesus of Nazareth. Jesus is believed by Christians to be the Son of God who came to Earth to save humanity. The catalyst for the spread of Christianity was Jesus' ministry, teachings, crucifixion, and resurrection. The early followers of Jesus, known as the apostles, played a crucial role in spreading the faith, and Christianity eventually became the largest religion in the world.
