A new, potentially polarizing theory

The idea of the Engineers building a research facility on LV-223 to study eggs found on LV-426 seems plausible to me. It would explain a lot about the substance too. Having a tough time with the rest though.

No Gavin. David did create the xenomorph in Alien Covenant and the black goo creates it not destroys. In Advent, the engineers is said to have renounced their ways, so how could David continue their work ?

Interesting theory! It would be an elaborate twist, turning the whole franchise on its head.

I've always hated the angle that Weyland-Yutani is nothing more than a greedy Weapons Division company. It's too shallow.

I prefer to think they are frantically trying to study the xenomorph to better understand how to combat the species.... and whoever the hell unleashed them in our galactic neck of the woods.

They will do whatever is necessary to protect the greater good. Crew Expendable.

Unfortunately I think David is a lost cause; too hell-bent on his vendetta against his any life with a soul. Maybe an anti-xenomorph agent was originally his directive, a directive that became corrupted during the Neutrino Blast? 

But, Peter Weyland +his company, as well as the Engineers could well be doing as you suggest.

I like it

It certainly sounds interesting; however, I think some elements might change the viewing experience of the Quadrilogy. With Alien for example, it would be strange watching it knowing Ellen was actually gumming up the works of WY who was only trying to save humanity. 

Indeed dk, it also changes our view of Carter Burke, Michael Bishop (Bishop II) and the scientists aboard the USM Auriga somewhat too.

Our current views could be correct if you consider how large Weyland Yutani is. A lot of powerful people having their own agendas could create different factions seeking the organism for different reasons. Some seeking it as a weapon and some seeking it for salvation.

No Offense intended, but seems very complex to me.

The earlier part about a Ancient Race could be introduced, because this was the Basis of the Concept from Star Beast. Were our Giant Dead Space Pilot was a Race who had came across the Eggs/Spores and was in the Process of taking them to the Ship for Study before they became infected.

ALIEN had intended to have a separate Egg Silo but at the time of Design, HR Giger had came in to create the Shared Aesthetic the Xenomorph and Derelict seemed to have and indeed its Pilot.   Indicating some Relationship between the Space Jockey, the Derelict and the Xenomorph.

After ALIEN we had Ridley Scott had mentioned the Ship was carrying a Bio-Weapon, but we can speculate to if this was a designed Weapon or something that they came across that they could use as such...  The Interesting thing was RS had mentioned the Space Jockey had performed a somewhat Heroic Act and Sacrifice in Quarantine the Cargo and Warning others about it.  I do also recall him mentioning the Space Jockey was Benevolent...  But then the Bio-Weapon is certainly NOT Benevolent...

But you could argue that in World War 2 the USA was a Benevolent Faction, but they used a Horrific Weapon that is anything but Benevolent... so maybe the Space Jockey had intended to use this Weapon for some Greater Good to Protect them from some Menacing None-Benevolent Foe.

Things change as they go along.... seems Plan A-Z never stays A-Z....   When we got to the Prequels.. from Jon Spaights Draft i get the interpretation that the Engineers had encountered something that they then attempted to Re-Engineer to create various Xenomorph Species.. and i am led to the Holloway Octopoid Creature was something the Engineers Discovered, and Experimented on... it would be like HOW we have David Create his Xenomorph from IN-PART the Neomorph Spores. 

Prometheus does muddy the waters a little, but if we consider Jon Spaights Scarabs as the Black Goo, and the Mural to Represent Sacrifice and NOTE.. it Originally was intended to have the Sacrificial Bowl on the Alter in front of the Mural.

Then this to me indicates the Engineers used the Goo on some Organism they had not Created, in a attempt to Create Bio-Weapons or/and extract and use Traits of the Organism to Evolve themselves.  This theory could still HOLD True in light of Alien Covenant.

I do think the Prequels open the Door to give us more of a Reason to Pursue the Xenomorph than just a Bio-Weapon... i think it points us to the Company being.

a) Controlled by AI/David and we are being played as Pawns.. so kind of like the Matrix... as in we are controlled by AI but we (most of us) are unaware and the AI Company are interested in the Xenomorph because its a Creation of one of their Own!

b) The company are aware of the Black Goo and its uses, and at some point there is NO-MORE of this stuff and so they are after the Xenomorph as a means to Try and Obtain the Black Goo from the Organism.

Back to the Benevolent Space Jockey...  the Race such as the Engineers could be Benevolent but they had NO-CHOICE to Protect themselves and other Creations from the Potential Corrupt Ways of Mankind.  They was trying to PULL THE PLUG on us before we could become a Threat!  Much like in Hindsight Weyland should have PULLED THE PLUG on his David/AI

The other thing to consider could be the Fallen Angels Aspect!  Where indeed those LV-223 Engineers could represent a Faction as such... while the Space Jockey represented a Benevolent Faction.

 A lot of powerful people having their own agendas could create different factions seeking the organism for different reasons. Some seeking it as a weapon and some seeking it for salvation.

For Weyland himself, he could have been using the former for practical and financial reasons to enable seeking the latter for purely personal reasons?

That makes sense. Exploit it in every possible way. If that were the case and his research was ever to be exposed he could claim he was seeking it with good intentions while having someone to take the fall for all the ill intentions.

As far as I know the alien franchise puts things from the real world and put into a fiction story. Maybe Weyland Yutani is a bit extreme but it is somewhat grounded in reality like Ripley as a whistle blower and WY that does what ever it can to get power a bit exaggerated in Alien maybe but still rooted in reality. A corporation that would be soulful or what ever would go bankrupt since it would lessen its profits so there fore I think that WY is a somewhat useful metaphor for a corporation in general and is far from the good guys. They might think about ethics but then they choose money when it all comes down because that is what they goal is, to get as much as possible so they us the Xeno for money and not for the common good. That is the corporate culture so they must do what ever they can to stay competitive so if they have to F someone over they do it.

They might try to make it so they use it for good while it is using it for bad in reality.

It is nothing there that suggests that they try to understand the Xeno for the better good. I think that Ripley’s ideas from Alien 3 still holds “they don’t give a fuck if a friend of yours has died” (something like that).

I think looking at it for being something they could try to harness for various purposes is most likely the best scenario, we only need to look at Davids work in Alien Covenant and he had basically spent years combining the best Traits of Various Organisms to accomplish his Xenomorph.

The Xenomorph is thus a combination of many Organisms most Perfect Traits and so from the Companies Stand Point, i think trying to Engineer These Traits for Medical, or Military Purposes makes more sense than just to obtain the Xenomorph as it is for the use as purely a Weapon.

If we ignore the David creates it ARC.... then we can ask the same of the Engineers... maybe the Xenomorph was a way to Harvest Traits of many kinds of Organisms... so the Space Jockey Race could then collect the Eggs or separate Egg Morphs (if we assume a Egg Morph does not make a Egg but a Cocoon of the Hosts DNA) so it may be used to destroy a Population but then leave behind Cocoons that can be Harvested for the DNA
