"A primal-cause is, by definitive default, the only determining factor of existence. Such a cause has no external needs or influences in the creation of effects occuring within it. If we apply reason to the term "primal cause", it soon becomes apparent that we are in fact talking about God itself." [original post, page 1]
The energy of such a primal-cause is shown to be free energy, since it is free from any external influences or internal obligations. The cause itself is shown to exhibit free will in the creation of the proceeding effects of time. It's rationally impossible to argue a case for the existence of a primal-cause that does not have free will. Hence, it's rationally impossible to argue for the existence of an entity which has free will, but lacks self-awareness and purpose.
It's very very easy to show why a primal-cause must = God.
