"Physics" isn't a force, but a description of the behavior of entities at a simple level. But as long as there are entities there are behaviors, existence implying identity, and this might as well be considered eternal.

Nicely stated. I'll try to expand it to see if I've understood it correctly.
1. 'the laws of physics' are descriptions. These descriptions have changed over the years but the behaviour of the universe simply hasn't. In a hundred years they may all be different. 'The Laws of Physics' don't have an existance except as our descriptions and are determined by us and the way we best understand things at the time.
To claim 'the laws of physics' make anything happen sounds about the same to a scientist as claiming telling someone religious that 'the laws of theology' make god do certain things.
2. Simple. Physics comes from the term 'physical'. Physics is now the science of the physical world with the complex bits chemistry and biology cut out and in seperate subjects, so physics is all the rest that isn't complex. It is as simple as it can be made. One atom at a time rather than a massive molecule or organism. But simple isn't easy, at least not for the sort of brains we've evolved to have.
3. There do appear to be a lot of distict entities (1 with 80 zeros behind it in our counting system, to count all the Fermions in the universe), and we detect these entities by their behaviours, which are imbalances in charge, magnetic moment etc.
4. Description. We describe. We each remember being very small and seeing others born later going through the same stage of being very small. We have a begining before which we remember nothing, and will have an end. The eternity of universe that went on before and will go on after is not capable of a complete subjective description.
5. Eternal. These behaviours don't seem to change in space of time even though some of the entities do. It would be interesting to debate whether the universe might actually last forever.
