[David Maes]

I believe also an idea like 'God' is not a person. A subject has limitations, a god shouldn't have them.
It would also explain the fact that we cannot really understand the idea of 'god'.

What I also wonder is why 'in a closed system energy always remains the same'.

Is God energy?

In former days, people believed in a 'vis vitalis'. Now, people have discovered it's actually energy, and it's everywhere.
(and it always remains the same).

Also we don't really see God. A person would be something we can see. (Or maybe he is more persons).

But we don't see him, so he's not a person.

If we wouldn't see him, and he is a person, then what we see is not real.
