Actualy i believe that it is said in one of the ancient monologues that they expanded in the galaxi and beyond..but i'm not exactly sure if that is the corect source.
Also TMan:"You're staring to sound like one of those Jehovas witnesses... waiving a book and a shouting a single line of text over and over." I find this rather insulting and quite far from the truth I dont know any of them (at least from the ones i know) that do that. Each arguement in this respective case is backed up by 3 or 4 different texts in diferent books of the Bible.
i dont care about a book on rules from a non exisisant being.
your all sounding like religous zealots imo, this is a game and someone said it themselves. i only presented enough proof on the shivans and the ancients to tell you that what happend, did happen and cant be changed, the race was destroyed and even if 1 survived, without reproduction its as good as dead(highly unlikey its offspring will reproduce with its mother).
what happend out there with the shivans and ancients is a massive battle on every scale imaginable, land, technological, space wars, superiority, etc. and in the end the ancients were killed because there weapons could not penerate the shield of any shivan, they had no shield of thier own, there ownage speeches is exactly what brought them down. is not impossible that the ancients were all killed, its very possible after all someone said something about a 'advanced space faring culture', and just look at what happend to vasuda,

of innocents died on that planet and only a handful escaped and without the terrans, the vasudans were as good as dead.
the ancients had no allies and could not rely on any race that was around, it could be possible that another race competly killed off the ancients but thats an entirly different matter, but the point is the ancients had nowhere to go, and had a knossos in construction and by the time any, if any convoys reached the knossos, the thing would be active and they would of escaped and shutting the knossos behind them, witch would explian the reasons the shivans destroyed Rivera station at Ross 128.
guess someone was right when they said 'the shivans are just as dependant on jump nodes as we are.' the shivans were trapped.
