Siddhartha Gautama, the father of Buddhism, was born over four hundred years before Jesus of Nazareth. He was the son of a royal family in what is now Nepal; the other was the son of a carpenter in what is now Israel.
Buddha developed his philosophy, called the Four Noble Truths and the Noble Eightfold Path. Christ did the same, developing his own philosophy and promising eternal salvation to those who believe it. Buddhism, like the Christian philosophy, has evolved through the years with varied interpretations and is now very different from the original.
Both have statues and monuments–fantastic representations of human imagination. Both were human beings, symbolising a spiritual principle. But only one has been elevated to the status of God.
