Theres so much mysteries in our world. Paranormal activity, reincarnation, seers and communication with the dead. Traits passed on from people who donated organs, etc. Its hard to say what happens, but when it comes down to it, we know what we ARE. We are a collection of electronics and photons, swirling around. We're completely energy, passing a temporary illusion of solid matter. Energy is never created nor destroyed. All the achievements of science can only pinpoint where our mind operates, but not what makes it operate. Our true essence has never been found by science.
