I don't know what I believe. I think that anything is possible. I can't really say that I have a strong belief of anything that cannot be proved. I have
ideas based on physics and sprinkled with hopes and dreams.
I'd like to think that our thoughts and well, our whole persona or "soul" remains when we die no matter what form it takes. Though, that is very difficult for me to believe

Sounds kind of morbid but, our bodies decay and we get consumed by other organisms. So, technically our energy still remains. And as 07gas has stated, it is said by scientists that energy is constant (is it a law gas?:? maybe). So, the energy that makes us work, if you will, remains. Where does it go? Who knows. I think it may just be reused as energy for other beings. And who knows, maybe in a way, we become that bird who ate the worm who ate the microorganism who ate from our body.
