Some 500 years before Jesus Christ, the Gautama Buddha, a prince who is considered the founder of Buddhism taught many doctrines that were very similar to what Jesus would teach five centuries later.
Numerous scholars have noted the undeniable similarities in teaching and doctrines between Jesus and Buddha, for example, the eminent New Testament scholar, Dr. Marcus Borg (who happens to be a liberal Christian himself) wrote “Jesus and Buddha: The Parallel Sayings” which aggregates hundreds of similarities in the teachings of Jesus and Buddha.
This certainly doesn’t mean the two are the same religion, but does this indicate that Jesus borrowed or stole ideas from Buddha? While there is some historical evidence that ideas from Buddhism reached Judea (and the western world) being brought back from Alexander the Great’s conquests, and some historians like Jerry H. Bentley argue that Buddhism influenced Christianity, this is not the consensus view.
In the end, this indicates that it’s very likely that kind/pacifist teachings and doctrines independently developed all around the world.
