The unseen force is there to be proven.. I myself believe they exist.. It  is down to whether it wanted to be seen or not only.. Certain people cant c it but they can felt it.. some can see it thus felt it.. v human, when v die, where do v go? Is there any spirit or soul left in us? Dont jus plant the thought of dead people go to either hell or heaven.. V bound to left some sort of spirit or unseen force behind when v left tis world when v r dead.. No 1 can prove it as no 1 dead can be come bac alive to tell u so.. Unless u r talking bout medium conversation..
