why do you propose we come from 'nothing'? obviously we came from the physical material or seed in our parents
why do you say 'energy' comes from 'outside the physical'? for example, for human society, energy comes from burning wood, burning oil, boiling water to create steam, burning coal, nuclear fission, etc. if energy was not related to the physical, we would not be cutting down trees, mining coal, uranium, oil, etc, obviously, the same as your life, which comes from the physical, energy also comes from the physical, including the heat of fire
also why do you equate 'energy' with 'sentience'? for example, reading a book predominantly requires sentience yet running a marathon requires predominantly energy
sentience is more of a mystery to explain. if you are a scientist, you can explain how non sentient communication occurs, for example, in computers
you seem to be asking from 'where' sentience comes from before even understanding what sentience actually is, i.e., how it operates based on cells, neurons, electrodes, etc
personally, i can't explain the neurology of sentience but maybe you look there first
for example, if certain parts of your brain are removed, will your sentience remain the same?
