Deos a soul exist?

Common belief is that after one dies soul leaves the body... and then perhaps a rebirth happens.

This leads me to thinking that even if we die our identity remains.. When Amar dies.. There would be a Amar's soul... This looks to me as the fscination of mankind to keep it alive even after death..

What I think is the source of life which exists in living beings.. goes out and merges into the common source of life.. There is no rebirth..

There is a common energy source .. after death there is no Mr X's soul..
