Freza, I get what you're saying. But from a 'scientific' point of view, everything in the Universe is made up of energy, that never dies and it never disappears, it simply changes from one thing to another. The human body is nothing more than a vessel for the energy of life, so when the body dies, the energy still exists in whatever form it then goes onto take.
Yes God and religion are two very different things, I firmly believe that you can have faith and a belief in a higher power and not belong to a religion. However I choose not to believe in either, never have, never will. It's just my personal opnion. Everyone else is free to believe whatever they choose.
Your avatar cracks me up by the way, can't help laughing at it.
