It was after she left the nunnery that she started to research God
They don't encourage people to ask questions like that in religious institutions.

Wikipedia has a potted version of it (not as colourful as mine, but it also namechecks Armstrong) here: en.wikipedia.org/wiki/God#History_of_monotheism

It seems fairly obvious that the Hebrews moved from polytheistic to monotheistic over time - the OT is crammed with records of the people going off and worshipping other gods. Why would they do that in a monotheistic society? Most religious people I know just stick to the one god.

Appropriate username, btw :)
