But all this "leave technology behind" makes no sense. You have all this clean, incredibly advanced technology from the cylons and they decide to leave it all behind. I very much prefer the "Wall-E" solution, in which, at the end, they rebuild humanity on earth with the help of robots.
Oh, and BTW, weren't skinjobs sylica-based lifeforms? Hera should be as well, at least in part. And they don't find that when they find her fossilized body? Pity this ending doesn't withstand the slightest analysis. Of course it's science-fiction, but even in this case, you have to be loyal to the bases you have established, and BSG clearly does not.
