What Happened to the Engineers on LV_223?

I think there is no sense in create theories out of the hat. It makes more sense to focus in what is showed in the movies or what Scott said in interviews. So there is this theory of two different faction among the engineers and I saw no clear evidence of that. Ok, the engineer at the first scene is different from the one sleeping in stasys, who seens to have some kind of exoskeleton. And the ships are different too. Ok. But if it was Earth in that first scene, or even another planet but a long time ago, lets say hundred of thousand years ago, I would expect then to evolve their engineering and to create a different project of starship in this "short" period of time. I would also expect then to evolve somehow as species or to develope a biomechanical armor that binds to their bodies. So, there is a lot of different explanations more plausible than imagine a civil war that we have no clue that could have happened.

Hi, Hadley's Hope. [quote]True. A lot of how you interpret the movie comes down to whether you assume that is Earth or not. There's nothing to show that it is, just our own guess, and of course that subliminal link in the following scene with the monolith that has a similar silhouette to the departing ship.[/quote] Ridley Scott was asked this. He said the planet may or may not be Earth. It was just to show the Engineers activities throughout the galaxy. [quote]Did you consider that perhaps they didn't create us? did you consider that whatever first visited us, we haven't seen it, and what was seen on LV 223- the Space Jockey may not be an Engineer, but the result of tampering with humans abducted on the visits to make strong, obedient slaves for dangerous work, like being sacrificed and working with that black goo, on a remote moon far from friends and family (no wife no kids... and centuries of sleep between jobs)[/quote] I had thought this also, however, Damon Lindelof has said that in the Alienverse the Engineers did create Mankind and that the Space Jockeys are the Engineers. He said the movie answered that question "definitely", though I don't recall where in the movie this is proven. If it is Shaw discovering the DNA match, that is a flimsy basis - that could just mean we came from the same source. Although, "flimsy" reasoning goes hand in hand with the thinking of nearly every scientist I've ever encountered :)

Holly fu@Y, Hadley! I was intirely missing the fact that the engineer do breath outside the domus.

If Engineers could breathe oxygen, why did they wore helmets upon entering the Ampule room? I think that Engineers hermeticly sealed chamber with Ampulies by manually activating green crystal which is a sort of mechanic lock that protect compound. When our team of loony scientists broke that seal they let oxygen to the room which, triggered series of fatal events. Pyramid is protected, but from who or what? That Alien did not hatched all by himself, but our creators set him free after they found out that "bad" Engineers are planning to erase us. Pyramid is protected by mechanism against Engineers or something very human like. I am not convinced that this type of protection was designed to keep Alien from escaping the Pyramid.

lots of great theories i think the jars contained life the black ooze was an industrial accident, caused by... someone mentioned why the other ships if it was an accident. they did battle the strange atmosphere there, perhaps the planet itself made all the jars leaky due to some electrical storm or something. anyone else notice... ground worms morphed into snakes humans morph into giant squid engineer + squid morphed into xenomorph one might say, there is more human to that xenomorph than meets the eye!

This is my theory over the back story of what happened on LV-223, this comes from reading the info posted on this site and some assumptions. The Engineer Monks vs. Engineer Warriors All engineers were part of a peaceful society. A "religious" group of engineer monks "seeded" life through out the universe/galaxies through self-sacrifice and the use of the black goo (aka the beginning scene triggers life) . The engineer monks had exclusive control of the black goo for good purposes. They had learned to extract it from the domestication of the xenomorphs (Xeno DNA). The engineer monks lived in temples all across the universe like LV-223. The engineer monks monitored the development of the human race, and showed the humans where their temples were located (aka paintings). At some point, another empire arose from the Engineer society, one that was evil and bent on destruction of the universe. This warrior faction wanted and needed the power of the black goo for evil purposes. They hunted and sacked all engineer monk temples. They chose to use the black goo for bio-weapons for destruction and bio-technology upgrades (aka the precious suit). As for LV-223, this was a temple that was attacked by a group of warrior engineers that were looking for the black goo. The first holograms activated by David show a groups of engineers in suits running toward the ampule room which is being locked down, hence why one engineer was beheaded. A likely scenario, is that the engineer monks at the temple fought back or may have performed some sort of self-sacrifice by unleashing the black goo on their attackers (a viral outbreak). This self-sacrifice by monks left the ampule room ripe with life (aka the earthworms). And it also resulted in the death of many warrior engineers (aka the pile of engineers in suits). Although the warriors were successful in overtaking the temple, only a few remained. They stocked piled their weapons and left the ampule room as a trap. The ampule room looks to have been a booby trap for anyone who tinkered into the temple. The remaining warrior engineers began preparations to leave for earth, but before take-off, an undetected black goo infection kills all but one engineer warrior who is already in a hyper-sleep chamber. Hence, the ship never takes off for earth. The lone engineer in cryo-sleep aboard the juggernaut is the sole survivor of the ordeal, when he is awakened he is naturally surprised to see the humans but then remembers his mission of destruction. Making more assumptions: it's possible that engineer monks have been wiped out or that there some sort of truce between the monk and warrior factions of the Engineer society.

Shane C, I agree with most of what you say, I don't see where you get the 'faction' element, however. I think, the layout of pillars in the room, is important, with the giant stone head in a central position. [img]http://www.houriganwebworks.com/images/Urns.png[/img] Is your faction idea based on the assumption that they are bringing this to Earth, rather than bringing humans to the chamber? It's never explained why all those urns are in the ship. Are they bringing them from where ever they are made, to restock the facility in LV 223, or are they meant to be deployed on their living cargo? They don't seem to be arranged in a way suitable for aerial dispersal, like bomb racks in a bomb bay.

You know, I have been hearing some things about the Engineers, being the divided into rival factions and perhaps a civil war was going on in the past. One the one hand I agree there isn't much evidence to support this. But when you think about it. With a possible sequel in mind. Imagine all Engineers are evil, and they all operate with the same single minded purpose. How would this work? Shaw and David end up on the Engineer Planet, there will be nothing but dangerous bio weapons and evil Engineers. How can they find answers in a world like that, or even survive? It would be a run-scared, action movie. Nothing like the first one. There has to be some kind of mediator between them and the Engineers, either Engineers who have good intentions, or yet a different race of aliens.

Well NYFM I'm thinking that what is being foreshadowed is that Shaw's allies will be Space Jockeys rebelling against their masters, who we have yet to meet. I don't think it's a faction thing between equals. There seems to be enough hints at a hierarchical society (like a hive) and the clues of alien abduction and slavery. It's possible that David switches side, to the 'superior' beings, and Shaw is left with a rag tag bunch of giant grey dudes, who are sick of being expendable. That would make it more than just a "run, hide, look for a flamethrower' type of movie.

@Hadley's Hope That actually sounds like a pretty plausible plot for a sequel. I do not trust that David. He was made before Ash probably, and according to Bishop from Aliens those older models were shaky :P I'm not saying by the way that I think Prometheus 2 would be a dumb action movie. I'm just supporting the theory of some possible ally they will find in either the Engineers or some other (sort of) friendly race.

These "Engineers" ain't all that. At least the dumb ass colonists on LV426 managed a last stand. I say we nuke their entire site from orbit... it's the only way to be sure there is never a PROMETHEUS 2.

Were they wiped out in response to their plan to kill us by their own kind ?

Outbreak Monkey, nuff said! =)

I have not seen a plausible explaination for why the Engineers(Dead) all ended up in a pile! Thats not what Aliens do it wreaks of the treatment your enemy would give you after killing you. And WHY where some chestbursted and others hole in the head killed. Maybe not the right place to put this but THE Alien we saw at the end was a completely new(Original?) design and I suspect does not yet have acid for blood!

In the sacrifice scene, the Engineer takes out a container that begins to bubble once in contact with air (i.e oxygen/nitrogen/carbon). It seems pretty much the same sorta black goo sealed away in those canopic jars at the Engineer HQ or Temple. The stuff that brings life from death, also can just bring death. The black goo is an exceedingly strong catalyst. As Hadley's Hope had mentioned in a previous post, the containers were placed in a "snare" formation" i.e the black goo remained stable until there was contact with air, delivered by any encroaching life-form, making it a prey for the creatures that dwell there. A perfect, bio-engineered experiment/weapon. Unfortunately, the Engineers (like the builders of Jurassic Park) did not leave room for chaos or chaotic interactions. Why an advanced civilization such as the one that the Engineers come from would leave out such an important factor in their calculations, a perfect world says a lot about their universe, literal and otherwise. Perhaps the Promethean Alien, was freeing his own people from that world, a world locked in a death spiral (presumtion here) due to its undying belief in perfection, humans perhaps seem to be just an evolutionary by-product. However, even little by-products have greater effect on final outcomes, just as David the Android might seem to play a greater part than one assummes at first in mankinds destruction/salvation. "Life finds a Way".

Oops..double post. Sorry

@ Robo Dwarf I believe Prometheus doesn't have enough steam to make a trilogy, but I really don't know much at this point. Just as we "descended" from "uber" DNA, the Aliens can be shown to have descended from us. And the rest is film history. [b]However unlike us, why would things made of the "same stuff" as Aliens want to consume us as food ?[/b] Is Ridley showing us why we destroyed our own legacy because of corporate greed etc. That Chaos (in the form of Weyland)and his daughter Nyx (Vickers) are repeating a similar chain of events from history, which we haven't learnt a lot from obviously. If the Engineers are "angels" and what we witnessed was an "angelic rebellion" or casting out, then who can we presume is God ? Is it a "source" of all living things, as in the Abrahamic God or is there a vacancy for that position and we witness instead the creation of the Demiurge of the Gnostics , presumably David.

Why did David infect Holloway? When we see David 'talking' to Weyland when he's in hyper sleep, Weyland presumably asks him 'what does the black goo do?' David says he 'doesn't know' and Weyland tells him to find out. So why pick holloway In particular....well I think it may be a case of being in the wrong place at the wrong time. David has been programmed not to feel emotions, and not to harm humans. ....but if you will recall he specifically asks David 'what would you do to get your answers, how far would you be willing to go?' (or words to that effect). To which holloway says 'anything'. In terms of David's logical computational thinking, holloway has simply AGREED to take part in David's crude experiment so he therefore sees nothing wrong with infecting him! Thoughts?

The Engineers were killed by ALIENS... But since when do we just find their victims in a pile? Why weren't they glued to the wall? If they died from chestbursters, how did they get impregnated? From facehuggers? From exposure to the black liquid? Where are all the dead facehuggers? Where are the eggs? Were they classic facehuggers or giant trilobite facehuggers? And most importantly, where are all the ALIENS now? Why did the Engineers seemingly die defenseless? They seemed to die in a panic. They died in a corridor, so whatever killed them was confined to a bottleneck... a problem that the Marines solved with the placement of a few Robotic Sentry Guns. PREDATORS can kill them with a freakin' spear. Do the Engineers possess weaponry of any kind? Is their only means of defense to tear your head off or just throw you into a room full of that black liquid crap and wait around a few hours for it to do whatever the hell it does to you? Could you just walk up and cap an Engineer? Would it be that easy to kill one? It makes no sense. So... The Engineers were not killed by ALIENS. So really then, ALIENS don't really have a whole lot to do with this movie. So why is this tied in with ALIEN in the first place?

OK, I'm just going to put it out here because its is staring me in the face waving a large banner which says "hello" To understand the fate of the Engineers, look at the shot in the "sacrificial" scene. It is [b]"The Fall"[/b], the guy LITERALLY FALLS, the fall of the Perfect from paradise for fraternizing with a lesser kind or messing with a verboten edict. It is the biblical fall or the Greek legend of Ephestus, for if one pays a little attention, these founding myths are common across cultures and often weave and borrow from each other. + Combine this with how elements of the periodic table affect each other + Exploring what it means to be human surely its not that hard, I'm just suprised that there isn't a mention of this anywhere on the threads, or if it is, then its a veiled one enclosed with metaphors of technology and corporate greed. At the center is Eve, Elizabeth Shaw. Perhaps.

All the engineers were killed by the only surviving engineer. Perhaps he infiltrated these groups of engineers as an enemy of their race, I read where the engineer’s race are to be strictly pure, of no sin, selfless acts performed by them for their race is what RS said in an interview by this critic, can’t remember where I read this, but from this site... Anyways, I think the living engineer did the deed and stacked the bodies there after assassinating them, so to speak. The photo appears to be a body dump, it’s exactly how those engineers are lying, as if dumped, they don’t lay in panic, but dumped, killed elsewhere and dumped, trust me on this one, dumped imho or not

no they were killed by a DEACON obviously IMHO and with all due respect.

I think there is a war going on here at the God level, as in God, Jesus , & Lucifer. Lucifer would stop at nothing to destroy Gods creation because he was looked over for "the" promotion. The best way to get back at God and Jesus is to kill us. This whole "Prometheus" thing is a Bible Story, and I really like it... Just my thoughts:)

Shanec, I think you're analysis on page 14 of this thread is extremely insightful and holds several truths. I see the Engineers as a civilization with "pure" intentions (first scene, creating life on earth) that went awry over the passage of time (LV-223 catastrophe). What was their purpose in experimenting with and dabbling in the black substance? I'm not sure. But I do believe the religious signals cannot be ignored... they are beginning to become the most intriguing part of this entire story.

Agreed Jack. There is no evidence (other than conjecture) that the Engineers want to destroy earth. Still think the Engineers are a race who after being used for perhaps thousands of years, by another race of creators, are punished for rebelling and all but destroyed by their makers. I reckon we will get some answers in Ridleys next installment. The thought of a "destroy all Humans scenario" is simply too, well too simple.

".....the religious signals cannot be ignored..." I take this to mean something beyond the Engineers' existance..that in their mind, is beyoind their life.. With the giant Human Head symbol..that is the obvious ..and most significant.. In any case they were not 'gods'..or 'immortals' in their own existance if they have religious symbols ..

"....Juggernaut Space Vessels.." Since we have only seen one Juggernout ship at a time..,,there must be scenes in future related movies that have fleets of them on patrol..being serviced...used in a proper Engineers' manner.. I just hope they explain the functional design(and power) of the 'U' shape design..

[quote][i]Since we have only seen one Juggernout ship at a time..,, I just hope they explain the functional design(and power) of the 'U' shape design..[/i][/quote] All I know for sure is they must have massive insurance premiums, the number of accidents they seem to end up in..

"...insurance premiums..' And throw in the Prometheus driving record..and you would really have a high 'Group Rate"

"...Still think the Engineers are a race who after being used for perhaps thousands of years, by another race of creators..." As we grapple with the various questions..I think we also include 'What is in the best interest of the Engineers..'Another race;..even XENOs??.. For all of the humans,that started this movie,,well only Shaw is left so survivial and revenge might be in her best interest... The 'GOO' presents a problem because the vast quantities of this substance,.in the interaction with various aliens,,seems like a wild card thrown into the universe as we know it, That effect does seem to be in the best interest of yet to be seen...entity... I just hope at the end on this story adventure we don't find it a 'dream'..when someone wakes up,,,and all we know is just what it has been so far...a story..

To answer the original thread question...all known what we call Engineers Died,,,There are no more,,,There was no hope and with their 'home' also gone they were trapped.. Shaw/David will find the next space port a gathering of other creatures/other worlds..where they actually do find the path to the 'Supreme Engineer'...

As LV420 posted June 28, “ALIENS don't really have a whole lot to do with this movie” and this is what Sir RS says, isn’t it? This movie is about our poking our noses into matters, literally and figuratively, which would never have bitten us if we had left well alone. And for what? The ******* impossible! The counterpoint to our scratching and poking around is the surviving Engineer who would never have posed a fatal threat to humanity if he’d been left to slumber on. The assumption we’re thrown in the movie is that LV223 is a WMD facility but that may just be a red herring dressed up as a character’s guess. As others have said, perhaps LV223 was an Intergalactic Centre for Infectious Diseases. So what did happen to those Engineers all those earth-years ago? Didn’t Shaw say something that others have considered foolish/foolhardy in respect to carrying weapons, “This is a scientific investigation.” She doesn’t know she’s in a Sci-Fi Horror show and neither did the Engineers. So were the Engineers developing a counter measure to xenomomorphism, to ward off being attacked by Aliens in the first place? Remember in Alien3 that Dr Clements was swiftly despatched by the xenomorph while Ripley was merely inspected. The creature detected that Ripley was infested and let her alone. Were the Engineers on LV223 then searching for a vaccine to fool xenomorphs into accepting Engineers as infested and so not attack them? This would assist the Engineers to recover the territories or worlds conquered by their weapon without being consumed by it. This might explain the Engineers’ actions in the playback and the meaning of the murals. They were desperately fleeing from a “Fifield” to a safe environment, a sterile chamber or Panic Room, when struck down by a lethally flawed attempt to vaccinate themselves against xenoism. The murals seem to be in the style of those medical charts showing the stages of a pathogen. It is unlikely that they changed their minds about eradicating humanity so was the sleeping Engineer expecting to be awoken by his colleagues as soon as their work was successful – i.e. they had developed both a viral weapon and a reliable vaccine - which is why he knelt down on being roused from his silent sleep. He was a pilot not a research scientist. Perhaps this explains why the Engineers’ colleagues back on their home planet didn’t try to discover what the h*** was going on at their LV223 base of operations: they got very cold feet. They’re like Bond villains, they try something once; it doesn’t work so they give up on it completely and move onto something else. Only they don’t seem to have tried anything at all for a very long time. I hope Prometheus doesn’t morph into another of those “dead civilisation” tales: the biter bit or the “Engineer” hoist with his own petard. Maybe Shaw and David are on their way … but that’s another thread. Other than that, who knows what their food is like and how safe their cooks’ hygiene standards are on such an isolated facility? They may have all simultaneously had a desperate need to get to the washroom and just not made it in time!

I'm going to put this out there The Engineer that survived did so because it wasn't biological. It was bio-mech, it may have also been an android itself? Cuddles wasn't bio-mech either, where as facehuggers are - as they seed bio-mech lifeforms The suit thing still bugs me to hell that it seems to intertwined with the Engineer's skin. Do maybe the Deacon is the first bio-mech as a result of this very first contact with a bio-mechanoid in the form of this Android-engineer

The Engineer that survived did so because his cryo chamber was not breached. They are masters of bio-engineering. If you recall, the original Space Jockey creature in Alien looked like its body had fused with the mechanism around it. If you want to call it a mechanism. I think in these movies the distinction between organic and mechanical is not as cut and dry as we are used to in 2012. I would hope to see a lot more weird stuff like that in a sequel.

But we've not established wether it was a breach from the inside or the outside yet.

I’ve got two shredders here: one is for stuff I need to shred into little tiny pieces for the usual security reasons in today’s cock-eyed world; and the other is for stuff I should on no account destroy. No, no. Stuff I absolutely must keep safe to control and keep track of what goes on. That’s the shredder I’ve named “The Lindelof”. Only joking! LOL. Then rub eyes and cry.

@MVMNT: If they were breached from the inside, the Engineers would have to have been impregnated before they got into their cryo chambers, then gone into chambers that failed in their design to put them into stasis. Not likely.

By breach however, I mean by any entity, happening. Not necessarily impregnation. I don't know if an exploding head makes up for much? Nor any other part of their body - as we see in the wall they are climbing up. Don't forget as well, Kane assumed he had a clean bill of health after the facehugger dropped off. Breakfast time was fun eh? So it could still happen. Ritual impregnation - the strongest survive in some kind of race to the ship - akin to sperm racing for an egg. One survives and carries on to another world "spreading the love" On the flip of this - I think that the effects that we saw on Holloway may have been overcoming them all, some it affected before others. However, the process of the Engineers head mutating/exploding seemed to be stopped when he was dead/lost his head before the event. Endless probablitlites, in this instance non of us are the wiser - purely speculation.

"..when he was dead/lost his head .." Was there many kind of timestamp on the holograph movies? I mdon't recall any mention in the various threads. Also was there any deterioration of the Engineers' head,,observed by the crew..before being electrified? At my movie showing there was a promo for the Tim Burton movie,,'Frankenweenie' They aslo used an electrifying system to bring back life into a dead form. Co-incidence?

Lots of good theories in here. Let me suggest my own. Chris, you stated something I think everyone should pay attention to - the head being examined on Prometheus. I'll get to that after I point this out - Antony - your link to the article explaining (speculative) plot hole answers and the like, is a good post, I like the way the writer exclaims that the Xeno's were pretty obviously already alive thousands of years previous to the events of Prometheus. However, I don't accredit this theory 100%. Not because of plot holes - but because of common sense. If the Xeno's were being engineered and made by the Engineers, then why would they have canisters of the Dark Matter and not Xenomorph Eggs? My theory is driven on just that. I do agree with his theory though. So let me conclude and tie it all together. I believe that the Dark Matter was used to make Xeno's, and that the Engineers had found that out a long time before Prometheus events. However, because Xeno's are so insane and viral, I think they chose to engineer the roots of what creates a Xeno-like creature. I say Xeno-like, because the Dark Matter obviously can affect a human, a worm, another creature, any host really. So my theory stems off that idea - the Dark Matter, IS the bioweapon, they obviously planted it and built it up on LV-223 and it was their holding grounds for their 'nuke' if you will. This was their defense weapon, to use against any species that posed a threat (or, maybe even if they wanted to just conquer other planets/galaxies). To add to this, the Xenomorph process took a LONG way to happen. David dropped Dark Matter in Holloway's drink, Holloway and Shaw have sex, and ONLY BY THIS METHOD does the squid-like creature that seems to evolve and reproduce the MOST come to life. And after all that, it still needs to infect and inject its own organic material into another host (Engineer) in order for the Xeno (or Xeno-LIKE creature) to finally be born. Because of all this, I think the Engineers realized and utilized the power of the Dark Matter as their main weapon, instead of going to all the trouble to build a Xeno army. Let me expand on that last part now. The Xeno-being-old theory stands, but only on a certain limitation. I think either A) the Xeno's were too much work or B) the Xeno (like humans) were an accident and weren't exactly a precise lab-test, but more of a freak-accident: a mixture of Dark Matter and any biological organism. Because of this, how could the Engineers sit and make Xeno's? Obviously they figured out ONE test that worked, which proves to be the ship that crashed on LV-426. But I don't think they had thousands of ships with Xeno Eggs. In fact, I bet that's the only one. And because of how dangerous the Xeno's are, I think the Engineers were really smart to leave 426 alone when their buddy crashed there. This is my theory. As with every/any one else's theories, it has loopholes too, but it seems to make the most sense. On a lighter note - lots of you (and other people/other forums) are questioning the hologram and the Engineers fleeing LV-223. While I was questioning this at first too, I think it's becoming less and less relevant - they OBVIOUSLY held an extremely dangerous superweapon on this planet, and when shit hit the fan and started killing off their own - they had to get out. To answer Chris' question earlier about the head on Prometheus - it had Dark Matter on it, not very clean and fresh, but already infected and infused with the head, covered by years of dust and preserved flesh, and once they stick their little needle-sensor tool into it to up some amps and trick the nervous system into thinking it's still alive - the Dark Matter starts acting up AS WELL, which, to me, perfectly explains a few things. The first - why the head explodes. The second, why the head explodes instead of infects further as it does on the human crew of Prometheus. The third, why the Engineers were leaving LV-223: their biological weapon got loose on themselves. However, the one who was still asleep obviously wanted to finish his 'mission' if you will, which is pointed out by David - Earth is a target. This all ties in to each other. Earth is the target because the Engineer at the beginning of the movie was an outcast, an exiled sinner, completely shunned from his kind because of something he did wrong. When he used their own powerful weapon to kill himself off (as commanded, I presume), his body left one small strand of DNA and it spawned humans. This explains why the awakened Engineer is so angry - we are a mistake, we were never meant to be created by the Engineers. The last big loophole to my theory here is the cave pictograms discovered at every ancient civilization. But I have a probable answer for that too. One of two scenarios, follow me here, I'm almost done. Scenario 1: The Engineers kept a close eye on us after our race spawned, and returned a few times to help teach/guide/watch/take notes on what the hell we've been doing. As time went on and we began to space travel and build nuclear weapons, maybe the theme here is the same as several other sci-fi movies - that the Engineers couldn't see humans destroy other planets - other galaxies - with our nuclear power. Maybe we have/are getting too powerful for our own good and could cause a problem for Engineers and other races. On a side note, maybe that monitoring of us led them to believe we might someday surpass their technological level and pose a threat. Scenario 2: The Engineers came back to Earth only a few times, way back when humans were still fairly new (ancient days) to give us a 'starmap' of where they were. Maybe they wanted us to come find them, and because it took so many hundreds of years for our own technology to advance, that they either A) felt abandoned/hated by us, meaning we hated our makers therefore what do we mean to them? ..... or B) quite simply, they were busy working on their superweapon and (until 2089 when we got to them) they simply hadn't made it back to Earth yet to destroy us. The last and final theory I have.... Scenario 3: The only Engineer we see alive, is the one that was in hyper-sleep. This leads to a whole other, final theory I have, (and kind of goes hand-in-hand with Scenario 1) that maybe the Engineers' homeplanet lost communication/contact with LV-223, but because of the danger and death of the Dark Matter on the planet, maybe they thought it best to leave well enough alone and not go back, in fear that the Dark Matter would return and destory themselves. And to go along with that, if this WAS/IS the last Engineer alive on LV-223, that would explain why Earth never got destroyed by the Engineers; the accident that killed off many of them on 223 held them from ever finalizing their 'mission' of killing us. Lots of speculation, but I think we're asking too many questions. In fact, that's part of why I love and find beauty in Prometheus so much - is all of these epic events lead to more questions, but the beauty is IN THOSE EVENTS themselves - the crash of the ship on LV-223, the spawn of a Xeno at the end of the film, the incredible strength of humans (most specifically Dr. Shaw and how she performs a cesarean procedure) all lead to one question nobody is asking or answering about Prometheus: why are there so many questions? This film is absolutely amazing, and very dark, but I just love how a lot of the events in the movie really tell the story of why, but many of us are asking why of other things in the universe, such as the first Alien. But really, it's more unrelated than we think, and that's not a bad thing. Prometheus and the content of it are a masterful way of depicting where humans came from, and possibly some of how/why Xeno's were brought about. But in an interview of Ridley Scott, he clearly explains that this is not a prequel and that to connect Prometheus to Alien, it'd be another 2-3 movies from here. It makes sense to me, why doesn't it make sense to anyone else? A lot has to happen! The Xeno-like creature at the end of Prometheus is NOT the Xeno's found on the first Alien. Lots of things need to happen first! Xeno eggs aren't even being transported yet by Engineers. Sequels and time will tell. But I hope I had some insight or new ideas for some of you to harp upon. If I have any bad or unreasonable theories, I'd love to discuss it with any of you that disagrees with me! Thanks for reading my ramblings on this garbage. Prometheus is my favorite film.
