The actual question was "Does Soul Exists?" (with some extra and unnecessary question marks!). And nobody, in my opinion has really got into what it really means. Perhaps because the main focus remained on the soul rather than the question (even of the one who posted it). Anyway, what the question presumes is that you have some basic principles of "Proving Existence of Anything" and then you put the soul into that principle and get the output.
But unfortunately, that's not the case. The question is enormously vague, firstly because we as humans by all our intelligence and magnificent genius cannot prove even the existence of a single micro particle, the reason being "frame of reference". Whenever we try to prove that something exist or is there, we use references like "he is in the room" , "the table is on the floor" etc. So, you cannot describe existence without a reference and because the reference again is a "thing" which needs a proof of existence, it becomes an infinite loop of proof and disproof.
Now we come to the part of soul, as you can now see we really have no way to even prove our own existence, we certainly cannot by any logic prove the existence of soul.
For those of you saying right now, "i eat, sleep and have sex with hot chicks and they really feel me up....how the hell you can say i don't exist?"...my friend, i used the word "LOGIC"

..lol..(by the way, sometimes you have to seriously forget logic! in order to really understand something). Anyway, i guess it's a question which is indirectly questioning the existence of God just like the question of "Evolution and Creationism", both directly question the existence of a supreme being and perhaps we don't want to discuss His existence, if not then simply......start a new thread!
So, this is what i can say about the "Question"
