When and where did Christianity start?


Christianity started in the land of Israel about 2000 years ago when the Saviour Jesus started preaching around 26 A.D. However, Christianity is based on the Holy Bible and this records events many centuries before that.  Adam was the first man that God created, and he worshipped the God of the Bible, the Creator of heaven and earth.  Abraham, the ancestor of the Hebrew people worshipped God in the Middle East about 4100 years ago. So the foundational beliefs of Christianity date from the earliest history of humankind. Buddhism started in India about 2500 years ago.
