I think that when you die you body is just an empty shell, but your mind still has some sort of latent energy that survives.
I dont believe in heaven or hell and I am not religious but I do believe that the human soul is some sort of energy, whether it be electrical or something else, and that can continue to exist.
a bit far out maybe lol, but you never know, Thats what I think ghosts and things are, energy released by the body at the time of death. you could get right deep into this if you think about it.
A little of topic is the string theory, where scientists belive there are actually 11 differernt dimensions, all moving through time at the same point but invisible to each other. I dont know if anyone has heard of it. But you never know, the energy that leaves your body could pass over into one of these dimensions.
Just a thought lol.
I think there is an afterlife of some sort, but whether its a Bible style heaven & hell i don't know. I think its probably something else thats less black & white. Thats not say i'm religious though (not athiest either).
And in some senses, reincarnation does exist in the form of mitochondrial DNA . Scientists are always discovering new things, for example the existence of brain tissue/memory cells in the human heart that has the ability to remember stuff. And this is a pretty new revelation! If we're still figuring out our own bodies who knows how much more we have to learn about just the very environment that surrounds us, let alone the more surreal physics & realities of space & time etc.
I would say i'm a scientifically minded person, but i also don't claim to have everything sussed and my eyes are always open to new possibilities, different abstract thinking etc. Stance-wise i'm agnostic. I always think its ironic when you have a group Athiests looking down on religion and its followers and saying to them "There is no proof that God exists, therefore he must not exist!"- but i could equally say its not been proven he doesn't exist! Science doesn't claim to have the answers to everything, its an ongoing process and no scientist worth his salt has said that science has proven or disproven god/s/high powers/whatever existence.
As ye olde Chinese saying goes; the more the wise man learns the more certainties he gives up in this world .
Its human nature to try and see things in a black & white matter, and in some sense some athiests & religious people are not that different from each i think (even though they both probably believe they're completely different from each other and much more enlightened in thinking & superior in belief than each other).
