Just because a large number of people believe in something does not necessarily make it right. For instance, till the 16th century most of the world believed that the Earth was the center of the universe. Yes, take the knowledge that Hinduism, Islam, Christianity etc have to offer, but dont bring phenomena like 'God' and 'Afterlife' into it. Let us believe in these when we see it, like in the rest of the sciences. People need to understand that they can live without faith.
