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.
Death may be prevented within the century, but religion will have nothing to do with it.

Yes it is not possible for religion to save us from death because we don't have any evidences of it. But because no evidence is yet found, it doesn't mean that it is not true. Science would possibly save us from death as our technology and knowledge were advancing right now. But, I would stick to a belief that faith would also be a way to be saved, although it is not yet proed right now.
