The Bahais see it that way too, Bill. They think that Mohammed and Jesus and Buddha and Zoroaster and Baha'Ullah and Krishna and all the other great prophets of history were sent at different times to different groups of people from the same divine source. Any reasonably open-minded religious person sees it that way in my opinion. The particular prophet that people are generally drawn to is simply the one they're already most familiar with through their family and their culture, and that's not surprising.

What is surprising is how many of them seem to get the bizarre notion that their particular prophet is the only right one! (not just for them, but for everybody) That's really a foolish attitude to take, and it leads to all kinds of strife.
