"Does that mean Hinduism is the crudest of religions that evolved into better forms such as Buddhism, Jainism, Sikhism and even Islam and Christianity? " Yes, it's evolution in everything including thinking or imagination, or what peopel call faith upon God and group themselves to practice it as a religion . All religions will themselves breakdown in the course of time and this is what you can see. Thre are already three Islamic fathis, two in Baudaism, some in Christianity ("Scientology" , a recent one), so all religion will die out sooner or later and new faiths will evolve, but there is no words like "better" that can be labelled to a faith compared to another one. faith is faith. it not the belief that needs at least a little clue to have one. conclusion: there won't be any existance of religion called Islam or Christianity or whatever in the present state in next 5000 years for sure. Perhaps, only one faith may exist with a only one God, "God and only God" by that time.
