Theory of Alien Origin and Engineer Culture

Deep Space
MemberFacehuggerApril 23, 2017OK, so just before the film is out I wanted to try and clarify my thoughts on the Engineers and their relationship with the Xeno/Goo. I'll try and be brief :)
The way I see it now the engineers seem to be a civilisation that could well be spread far and wide across the galaxy. It makes me wonder if there was an 'original' or what you might call the 'top' race or another group of beings altogether that kick started the whole thing.
It would also seem that part of their culture is to use the goo, alongside a sacrifice, to create new variants or culture groups within the overall civilistation. Basically: sacrifice + goo + humanoid = new race (Earthlings as an e.g.)
THis has been repeated across the universe for a long time; hence the cave paintings which could be designed or intended to show links to a wider world . . .
AS we have seen though it would appear at least one faction had some grand ideas, or sought dominance or greater control, alpha status etc over the whole of the wider civilisation - hence they created the xeno or used the goo as a weapon.
Some kind of war started which is what I think led to LV223. I'm still not sure if this was built for benign or destructive purposes but it does look as if whoever was there ran into some trouble - possibly via sabotage or infiltration?
This then leads us where we are now. Humans finding what seems to be remnants of an old(ish) war and clues that point to the creation of the xeno and possible misuse of the black goo
There's nothing new here really but given the new footage and images it is clear that at least some remnants of the engineer culture (or derivatives of it) remain. At least until David showed up anyway ;) Poor SoB's!
My thinking is that what we see of the xeno in AC is due to David reverse engineering, if you like, and creating it that way from an old recipe! Put simply, the engineers created the xeno to wipe out the competition or threat that they thought other humanoids could be . . .
What do you guys and girls think? What are your thoughts now on the origin of the xeno and how this relates to the engineer culture?
