Buddhism is generally considered to be older than Christianity.
* Buddhism: Founded by Siddhartha Gautama (the Buddha) around the 6th century BCE (approximately 563-483 BCE) in ancient India.
* Christianity: Based on the teachings of Jesus Christ, who lived in the 1st century CE (approximately 4 BCE – 30 CE) in Roman Judea.
Therefore, Buddhism predates Christianity by about 500 years.
