There was a lot of relgious imagery on the original BG. Much of it Jewish

Mormon, actually. Any Judaism was mostly likely by derivation only.

You're both wrong. It was Egyptian. Lots of references to pyramids, sphinxes, hieroglyphics and the like. Even the helmets looks like Egyptian pharaoh headdress. As the series evolved it became very clear that earlier colonists (not the wandering colonists escaping the Cylons) were involved in helping to advance the people here on Earth by teaching us advanced science and mathematics and building various things, such as the Egyptian pyramids. This was the time when ancient astronauts was a big fad.
