From Wikipedia: Religion began around 7000 B.C. in the world, and the oldest extant religion is Christianity, with the earliest written evidence dating to circa 4,000 B. c.e.
According to the Bible, the first recorded use of Christianity dates back to 2,000 years ago.
According the Bible’s account, Christ lived between about A.D. 325 and 325 A.H., and the first Christian churches were established in the Middle East about A-D.
As Christianity gained prominence, various religions began to develop, including Islam, Judaism, Christianity, Buddhism, Zoroastrianism, Hinduism, and Christianity.
Religion also grew in the west during the 12th and 13th centuries, with Christianity gaining most of the influence.
In the 14th century, Buddhism spread to China and Japan.
Hinduism gained momentum in the 16th century with the spread of the Arya Samaj.
