SeerSGB, so perhaps the scriptures themselves pre-date Kobol. They may have originated on Earth-Prime and were updated/changed over the thousands of years that followed. It would explain Pythia, how the scriptures had the details to get to Earth. It's not because Pythia went to Earth with the 13th Tribe, but because Pythia actually went to Kobol in the long-forgotten Exodus from Earth-Prime.
I like this.
Basically yeah. The "Scriptures" might just be a record of the exodus from Earth-Prime that's been romanticized over the years till it became myth and religion.
Hell we [Earth Prime] could have made the first Cylons and had to run for it just like Kobol and the Colonies had too.
