Religion does not really save someone. It is having faith in what you believe in that can really save you
And again save you from what? Death?
Remember that Death is inevitable, what happens after that? Nothing.
As people say, no one really fear death, they fear the unknown. Religion is a thing from past, that people just can't get rid of. Even if you look at Christianity now, you'd think they would be very heretical in the eyes of medieval (renaissance even) Christians. It's evolving to be more pleasing to the mind of people, but still, do we really need it? We are rather abundant for mind distractions now, in my opinion, and religion is just one of the many.
