I agree with Preppy, that
[details=Spoiler]The cave paintings make literally zero sense. They imply that the engis gave people knowledge of that particular place in space. A place that was just a tiny outpost. An outpost built specifically to create bioweapons to wipe out earth. At least if what David saw was accurate.
Also, Irdra’s character had nuance, and, it was strongly implied, a military background of sorts. He was the one who pieced together that the moon base was an installation created far from the Engi’s home. This too, makes sense, given what we see.
However, there is also the fact that there were many ships on that moon - not just one.
Wouldn’t this seem to suggest that the moon base was more than merely a place to design the end of Earth?
We are accidental, that much I think is given. Not leastly because we are supposedly genetically identical to them. Not just similar, per all life is connected at some level - genetically identical. We are them, come again.
And yet not, perhaps, because, as someone else in here mentioned, the humans showed the most decency, compassion, love, care for others, etc, of any of the species shown.
Maybe we are them before they bred down a path without pathos?
I also do not believe that they intended to wipe us out for fear of us. If anything, it seemed a matter of arrogance on their part, like they saw themselves as gods, and thus entitled to do as they please. A very savage, violent, and utterly casually cruel race, all in all.
But yeah. Cave paintings make zero sense… why show us the Space Nazi germ warfare production site’s location?[/details]
