But hasn't science in some way proven the existence
It is now known as a scientific fact that , matter is never and can never be destroyed only changed into a new state of being.

The religious believe this proves that when we die,our matter {soul} is released from our body.

No I am not religious zealot that believes it but a question should be raised all people of the world , going back to the first people here have believed in something. Even reincarnation is a transferance of matter. If science wasn't even known then , why did all people believe that you went somewhere... Even before religion this belief existed.
