I think I agree with you, flyingfish. Not trying to get religious or anything here, but I believe the soul is a form of energy, and although science hasn't exactly proven anything on this matter, I do think there are hints here and there.
.... .. ..energy cannot be destroyed or created, implying that the energy is already existent and only that it needs to be harnessed in a way that ignites it into the physical plane. So then, I thought, if the energy that exists within our bodies disappears after we die, it is only really fading into another plane of existence invisible to this world in which we live. At least that's my theory.
