That's the same question as "Where did the big bang come from?" The answer is complicated. God always was is still the working answer I believe.
ummmm no, it's not the same question, darlin. Ok, let's break this down.
a) we have the big bang caused by natural forces colliding with one another and finally releasing in an explosion that sends the building blocks of life into an ever expanding universe *very simplified version*
b) a singular intelligent force that physically created everything, but this intelligent force appeared out of nowhere and had no beginning
One is caused by purely natural forces, like an earthquake, and one has circular quasi-logic written all over it.
So yeah, not the same question at all which leads me back to my question which is where did this intelligent force come from? You must have a theory on it :)
