Lets link Prometheus to the Alien Universe

1) Its shows the Derelict are the same kinds of craft, it is not the same one that lands on LV 426 though and i doubt that Shaw and Davids one also lands on LV 426. I would assume the Derelict in Alien has been there for over 2000 years by the time Nostromo's Crew find it. 2) I agree that the Black Substance can be used as a Weapon, but i am not sure that the exact purpose of it is intended for that, just the Engineers abused the substance that was used to create life, to then create other experiments. I dont think the Worm things are the basic form or anything, i think the worms may be something the crew may had brought into the ship from outside the temple. My theory and thus not FACT, is that maybe the substance that the Sacrifice Engineer used to break down his DNA into a substance that can then become the building blocks to mutate and create lifeforms that carry some DNA traits of the Engineer. If this is what the substance did, then surely if they wanted to they could have have captured the matter that was broken down from the Engineer and contain the broken down Engineer DNA into a Canister rather than let it dilute into the Water Fall. This brings me to the Xeno, i assume it is a life form they found or created, that was very difficult to contain, control and store... Storing Alien Eggs has very huge risks..... So maybe they used the same substance that the Sacrificial Engineer used, on the Xeno to break down its DNA and contain it into the Urn/Canisters. I thus propose that the Urns Black Goo is derived from Alien broken down Xeno DNA as opposed to created from it. 3) As above i think the Canisters are used to store broken down DNA of the Xeno, that can then be used to create and mutate organisms into organisms that carry the Xeno Bio Weapons DNA. As a safer way to store and deploy a Bio Weapon with similar traits to the Xeno. 4) Agree, i think they messed about with the Black Goo in ways that it may not have been intended, we still do not know why they wanted to create us to kill us... and create us to use as hosts for Xenos is well pointless. So i assume that the Engineers on LV 223 Stole/Abused the Black Stuff from the others or higher power/creators from their home world... this would explains some potential plot holes as i propose that either. a) The Engineers/Creators on the Home World do not know about the creation of Man, or maybe Even LV 223. b) Maybe they do but they had been wiped out... i.e a rogue faction created the Xeno to wipe out their home world/creators. c) A failed attempt of b).... 5) Well returning to Earth would lead to plot holes as far as Aliens universe as then Earth/Weyland Ind etc would have seen a Derelict.... Maybe the Engineers are dead... but then with no Engineers or Humans, Prometheus 2 would be a bland movie of David and Shaw.... I assume they find Engineers, who maybe do not even know what happened on Earth or LV 223... as surely if the home world wanted Mankind Dead then why had they not sent missions to see the status of the LV 223 outpost and if it had succeeded in its mission. Shaw turns up with decapitated David, to a World Full of either Engineers who want us dead, or Xenos or killed them off.... doubt Shaw and David would last long in any case. 6) I dont think Weyland knew 100% in Alien what they was dealing with as far as Xenos.... i think they would have some idea that the crew of Prometheus had found something that could be used as a Bio Weapon. Maybe they find Shaws Message prior to sending out Nostromo who knows. I would assume that after the events of Prometheus and Prior to Alien something happens to LV 223 so as that there is nothing left to explore or find. This would be scope to have it covered in Prometheus 2 or 3.

As far as the Xeno Deacon.... I think it was there to give us a hint of what kind of life form can be created as a series of events regarding the Urns contents and interaction with lifeforms. It is something that can not be ruled out as the Proto Xeno but then also something that does not get explained to be as such, so its left open. I think that was the whole idea of the ambiguity, as the Mural looks like the Deacon but also has Face Huggers, they are teasing us with clues that can contradict so as that we cant get a 100% answer and so we have to speculate and assume. As far as links to Alien, well basically its some back ground on Weyland, who the Engineers/Space Jockey was (only not in Detail, thats where Prometheus 2 comes in) what the Derelict Ships seemed to be used for, and that some how the Black Substance in those Urns is connected DNA wise to the Xeno, but is it a substance that can create and has created Xenos in the past, or a substance derived from the Xeno? Maybe Prometheus 3 would give us that answer.

@ShinobiX9X Ridley has now said what the Derelict on LV 426 was, and maybe he could have shown what he has stated for the reasons it landed on LV 426 in Prometheus. All they had to show was a flash back scene with no date... so we dont know if its in past, present or future to Prometheus... shown a Derelict in Space, show it heading to a Gas Giant with 4 moons.... then pan to the Cargo Hold with Xeno Eggs and show one either.... Open already, or better show one open up and we got to see the fingers of the Face Hugger but thats it. No Xeno, No Full Face Hugger, No Fave Hug Scene or Chest Buster, No scene of the Engineer or who was in the suit....... This would give more of a clue, but still have the mystery.. The above in a scene would had made some happy... but Ridley has already said the above and why, here is what he hinted at. 1) The Derelict was carrying a Bio Weapon Cargo of Eggs. 2) It was heading to a destination (does not say where) but one of the Cargo got lose. 3) These caused the Pilot to have to set the Derelict down on LV426 it was not the intended destination and had to make a unplanned and crash landing. 4) This occurred a few hundred years prior to the events/outbreak on LV 223 that happened around 2000 years ago. From those clues Ridley had given and those in Prometheus and Alien we are then and now left with these questions that may never be answered. 1) Where was that Derelict going and Why? 2) How and when was the Xeno created and Why?

Ultimately I am assuming that what ever got those jockeys on Lv 223 got our pilot on the derelict at the same time? so there is a time factor involved. I found it interesting that all the pile of dead jockeys had Helmets and where did all those guys go in the Head room once the door closed. UMmmmm PORTAL Once your snorked your dorked. If the temples are used to produce and store these canisters with bio-altering goo could it be possible that facehuggers are produced somewhere else or from the same place? Leaving the question is the derelict going or leaving the LV sector of space. I still like the original idea they had of the Eggs sacks having tentacles and moved around on the derelict. Perhaps the derelict it's self uses the canisters to product the eggs and humans are produced somewhere else to make Xenos.
