If you are an Atheist - what happens after we die? Watch
All the evidence suggests that consciousness is the result of brain activity, this stops when you die, so probably no afterlife. Although, we don't know an awful amount about our consciousness and I've never died, so
Your consciousness isn't a thing that can be transferred.
I really like the idea that your consciousness settles in another body, oblivious of its past life (not the same soul or anything, just that our focus shifts to a different awareness, kinda) but there's no reason for me to think it's true. I just wish it were!
I am. We decompose (I.E., the worms, and all sort of other weird and wonderful creatures consume our lifeless body).
