I'm not sure if you understand what you're insinuating here.

You cite the first law of thermodynamics and then go on to suggest that energy can take on another form (presumably through "reincarnation") but you do not explain the mechanism for this. Yes I do understand what I have said here.
The first law of thermodynamics is a fact scientifically, and since this is true, what's to say that the energy which we consider life/consciousness doesn't carry on into some other form. I did not state reincarnation in my post. I only said what if it takes another form.

The breaking of chemical bonds results in the release of energy back into the organic world. Any energy lost by a system must be gained by the surroundings. There is nothing spiritual about this. It is a physical process. You have also just stated here that the energy does still exist in a different form. It is no longer in the human body, but in another organic state. And you're right there is no spirituality involved there. But it is still the life energy of the deceased person. Correct?

Some energy remains in the body at death, which is why it is possible to burn a corpse, as the deceased form will convert its chemical potential into thermal energy. Energy is emitted as heat as the body decomposes. I'm confused here, it is possible to burn anything, and decomposing is not burning.

Furthermore, the brain's energy is electrochemical in nature. When an individual dies, the energy in neurons, produced with the assistance of ions that help create an electrical potential at the cellular level, diffuses. That energy may be consumed by detritivores or recycled as heat. Once again you are just restating what I said and you said in the first part of this post. The energy is not destroyed just changes form.

There is no place for God in all this. Please look at what I wrote, I did say depends on what you believe. Which also included Karma or a Deity.
If I remember correctly you do not believe in rebirth, I do and so we will not agree here.

The Buddha did not teach that energy persists from one body to another, like a transmigrating soul. Even if it did, nothing like a God exists to guide the process. No he did not, but he spoke of rebirths in lower or higher realms which our Karma causes the mind/consciousness to experience.
