Actually, at this point it would be considered a hypothesis. Once we find a way to test the hypothesis and have it confirmed it might be elevated to the status of a theory. Do you have a method for testing for the soul?

Your are not going to like it but YES!
And thus we come to a parting of the philosophical ways between science and religion...
ENTER OVERSIMPLIFIED STEREOTYPE 1:
Science can't measure it, so it is not 'falsifiable'. From there, well, we can't have supernatural entities mucking up our experiments (except Maxwell's demon :-0) !!), so let's assume they don't exist (at least for the purpose of the theories).
Pretty soon we have theories that handle things pretty well, so who needs these supernatural leftovers to explain things?
There, have I cheesed off both sides pretty well now? :-)
