I kinda wish we didn't know that... I mean, it makes sense when you look at the storyline progression - it did seem to be building towards something ancienty... but I dunno how [V] would have managed to tell a good story with the ancients. Either they're 8000 years more advanced than we are, and so we've not got a hope in hell against them, or they're on par with, say, the Shivans, which seems a little lame for a species who've had 8000 years to develop.
But, well, I suppose B5 told awesome stories with super-advanced aliens, so maybe they could have pulled it off.
