Great idea, Seraph, and thanks for all the hard work.
Alas, I have to take issue right at the start on on point #1!!!
Is there evidence to support this? Apart from the ‘Sacred Scrolls’ and the ‘Book of Pythia’?
In fact, I have a massive problem with humans ‘evolving’ anywhere but on Earth, or the BSG-verse Earth-analogue.
Simply put, the likelihood of life following an evolutionary path essentially identical to ‘Earth’s’ and reaching a point where there are warm-blooded placental animals resembling humans, is effectively zero. There have been so many contingent events over some four billion years contributing to what we call ‘humans’ that it is inconceivable this would even be remotely mirrored anywhere else in the universe.
Now… before you all yell: “But this is fiction, and it’s not our universe, and it’s BSG!”… before you all think and yell this (almost valid-seeming point); this is not correct.
BSG’s universe, in nearly every aspect reflects our universe. The laws of physics seem pretty much the same. Biology likewise. Geology. Astronomy. Hell, even human sociology! And psychology.
And wait… there is an Earth. I’m trying to imagine by what convoluted means BSG’s writers would have either: 1) humans evolving identically independently on different planets, or 2) evolving on Kobol, and then colonising Earth.
- As I mentioned earlier, this is just too unlikely. Especially as we have had no evidence of their being any advanced extraterrestrial life anywhere in the galaxy. (It is even possible, in fact, likely, that the human-colonised planets were ‘seeded’ by the visitors themselves, and that there has never been any non-terrestrial life form discovered.)
Thus, having this happen would contradict both the real universe (ours), as well as BSG’s created universe, which is so similar to ours.
- OK, in this case Kobol was the origin of humans. But, due to contingency, it must also have been the origin for all the things which make humans work: bacteria, plants, animals, in fact, everything which is currently on earth! Thus, Kobol is an Earth-analogue, and the ‘Earth’ of the BSG-verse just another rock which was settled, terraformed, etc.
But this just is not logical. There would be no purpose. “That which we call a rose. By any other name would smell as sweet.” Why would writers create an ‘identical Earth’, fiddle around with history, when such effort would actually produce nothing? Why not simply say… Originally, humans evolved on Earth. At some time they developed space travel. They colonised Kobol.
Then… you can have your timeline points from 2… xx.
Finally, I guess we have to get to the ‘Sacred Scrolls’ bit.
To me this is a nice analogy to belief in ‘our’ real Earth. Millions of people on our planet currently actually literally believe - despite mountains of real, hard concrete evidence, collected, analysed, interpreted, experimented upon, tested, and confirmed over centuries by thousands of the most capable and intelligent humans who have ever lived - that the obscure oft-translated (and mis-translated) unconfirmed, un-externally-corroborated, ignorant two thousand year-old parchment scribblings of shepherds, fishermen, convicted criminals, misogynists, war-mongerers, hate-filled racists, child-abusers, mystics and drug addicts is somehow superior and more ‘inspired’ or more valid in explaining the universe.
(Whew… that felt good… 
Why would we expect the BSG writers to not highlight this? There has already been much questioning of ‘faith’, the nature of religion, the meaning of prophecy, etc, in BSG. Why would we expect the BSG universe’s ancient ramblings be any more valid than our own?
Well, perhaps for some cute dramatic purposes there might be some nice coincidences, and alignments, but I reckon four years of pretty hard science, and recent solid explanations knock big holes in the BSG mystics.
Pythia is about as relevant to the BSG universe as Revelations is to ours: ie, it is only important if people give it importance.
