[Supernatural]What were God and the Angels doing during the reign of the Pagan Gods?

You assume that the two situations are mutually exclusive. Monotheism, in various guises, has existed, conflicted and coexisted with so called 'pagans' for more than 4000 years, and both sides have influenced each other.

There is also nothing realy to indicate that either God, nor the Hosts of Heaven have fostered any particular faith, while the pagan gods have actively encouraged their cults. 

Considering the reactions of the two known prophets, and the association with the Aramaic faiths and their prophets, that the development of most related faiths were not formed by divine Mandate, but rather by Prophets tripping the eff out because they couldn't properly understand their gifts.

So, in short... Basically nothing, because they didn't really care to interfere. As Death says, this is a Petri Dish, and what good is an experement if you're always poking at it?
