And before that? Has the universe always existed in some form with the present energy level? What about before the big bang?
Quite frankly your point just avoids the problem, all the energy came originally from something.
Actually some of the present theories propose that the energy cancels out, so you effectively get the biggest free lunch ever.
That was related to the universe adding or removing energy as opposed to the where it came from.
We simply have no way to know what happened right at the start, or prior to the start of the universe (anything before the Planck epoch at about 10^-43 seconds in).
Yet.
Part of the problem too is that, as mere mortals (scientifically speaking), we have no way to conceptually think of the start of the universe, especially if you take the view that time starts with the big bang too. ie there is no "before".
However, to vaguely drag this back on topic, lack of knowledge is zero reason to say "it was god wot done it".
