Guys you should attend Zakir Naik's "Similarities between hinduism and Islam" if you can. If not, buy the DVD.

All real religions come from one God. They change at the whims of men.
Then what about people who are culturally Hindu but also atheist like me. I am fine with the concept that we have three main Gods namely Brahma, Vishnu and Mahesh who create,take care and ends the different universe cycles and there is no need to find prophet in hinduism.
Culturally hindu means I like to follow our culture, I love my Gods but in the end I am atheist also. So if my religion gives me freedom to remain as freethinker then why should I look to change it?
