Well, Buddhism did. There are a couple billion Buddhists. As for Jainism, its not really normal or healthy to be a vegan, which is required by Jainism. Too hard for most people.

If that's asking why Jainism and Buddhism didn't spread, it's probably because they, like Judaism, don't advocate actively converting people to their religions. Christians and Muslims, among other religions, make a point of using missionaries, etc. to spread their religions to new places.

actually there are about 800 million Buddhists> i be live Jainism has under 20 million adherents. I would describe Buddhism as a cultural "way of life" describing groups of people in Asia> I don't think those religions appeal to alto of people and those religions tend to "stick" in certain areas instead of crossing the globe>
