Think I figured it out

I am surprised nobody hit on this idea completely and forgive me if there has been some talk of it that I missed. I think I have figured out what is going to happen. Most people feel that David is involved in the creation of the Xeno species and I believe that is the case. Nobody has gone into any detail as to why though. 

It just hit me after watching Prometheus again. I feel David will be the creator and here is why;

David was created by humans

Humans were created by Engineers

Humans then became a target (for vague reasons- unless you follow the Jesus theory) to be destroyed by their creators

David witnessed the humans interaction (and took large part) with the surviving engineer.

In surviving this encounter, he probably realizes the cycle and feels like maybe when the humans come to where he is, they will be trying to do the same thing. To destroy their creation.

Leading to a large hatred towards his creators

David has already played biological games

Walter is probably seen as a competitive entity to him

Between his growing hatred towards humans and probably hostility towards Walter, he decides he needs to kill his creators before they destroy him

Therefore leading to doing away with Walter, mixing part of his being with an already established alien being on the planet to create a biological weapon. Probably using the goo or some other element on the planet.

This could lead to him wanting to go back to Earth to destroy humans in whole. 

Something happens and David may be infected as well.

It leads me to believe that the Space Jockey would be David. With something happening to prevent him from carrying out his plan whether due to another humans interference or something else.

Sorry this was long for my first post but I felt like I needed to share it. Let me know what any of you think or if it sparks something else to add. 

Welcome. I am pretty new too.

Your thoughts are pretty much on board with others who have posted similar ideas. I also thought it would be possible that David could be the SJ and birthed the original biomechanical Xeno in Alien. The problem is the time line which I haven't followed as meticulously as others. Someone pointed out the possibility that RS might retcon it anyway. In the late 1970s I doubt he thought the story would get this big.

It would be a good story but the space jockey had been dead for 2000 years...can't see how you could retcon that...an intriguing lone of dialogue in original alien film that gets our imaginations flowing but prevents tiring directly to prequels as within 100 yrs apart

Actually, they don't know how old the Space Jockey was. Dallas only says "it looks fossilized". The ones on the other moon in Prometheus were dated 2000 years old.  It doesn't mean both moons sets were the same time 

If ridley screws the timeline it would ruin the whole mythology of alien universe....what if the prequels tie into original by in last film David arrived on lv 426 and investigated derilect craft and activated the sos signal as he found that the alien life cycle on this moon had reached its peak and he wanted to see the perfect organisms at work so sends signal to get people to arrive and watch it unfold

The Peter Weyland files on the Prometheus Blu ray are considered canon by most of the community, and Fox seems to want it that way. They state that the transmission from 426 was recieved and decoded before Prometheus left and it was an alternate destination if 223 didn't work out. Especially since they orbit the same gas giant.

 two things are set in stone even with filmed, theatrical cuts of alien and Prometheus:

1 426 and 223 are in the same system. Zeta 2 Reticuli.

2: Shaw and David  clearly went into hyperspace at the end of Prometheus, so Paradise is not

This is where things get complicated. Without the Blu ray extras, we have to assume the message from 426 was NOT transmitting because nothing in the filmed record shows David recieving it. This is a MASSIVE plot hole. And he would have at least had a conversation with Weyland about it. There is also a holographic film embedded in Aliens Colonial Marines that actually is canon that shows a ship shooting the juggernaut down after a short battle. The victorious ship is not a known human configuration. So why would David go back to the Zeta 2 Reticuli system with a cargo full of eggs and who shot him down? All the engineers on Paradise are clearly dead.

How does that fit into the covenant narrative? And how would he get chest bursted or face hugged in the first place when he is made ENTIRELY of inorganic material. The signal could just be a pre-recorded fail safe, so that's why it's in Engineer, but a xeno gestating inside him at all is a problem.  The sheer size of the figure in that suit is another issue.

Want proof about androids not getting face hugged? Martin is standing near several eggs in the trailer when Crudup's face gets a hugger. None of them open. Images edited and provided by Big Dave.

If you go to the Prometheus website. Weyland knew about lv 223 and lv 426 ( beacon ) way before they left from earth..it's part of the movie story line if that helps.

i thought David may be the creator of the Xenos but if you dig into the details the xeno's are ancient just like the engineers ( mural )

i do think David awakens it though..

I agree that the Xenos on the surface of Paradise are probably because of David.

Welcome aboard...

And yes its been discussed before... i even discused and though this was the case in March 2012 before Prometheus and then since we had the Synopis of Synthetic David and also after the Fassbender plays Doupleganger and David information

I was led to think maybe a Non-Synthetic David (by evolution for Prometheus.... or then Advanced Walter Synthetic Construct)  would ultimately maybe lead to the Xeno Bio-Mechanics..

Its logical.. apart from the age of the Space Jockey.. which is not Fact as to its Age... so they could retcon that the event is not thousands of years old (unless they use some kind of Space Anomaly leads to Time Travel rubbish..).

THE FRANCHISE.. is a in-coherent mess... ist flawed... its left so contradicting and ambiguous and open to interpretation.. much like the Bible is lol

Its a case of will they finally decide on whats canon and whats not and go with a set A-Z of clues to provide its Canon... so we know which stuff to ignore and which to not..

But i think a few things people over look.

1) The Derelict is more Organic than Juggernaught, yet its Cargo is more Mechanical as far as end product than those shown in Prometheus and Produced by the Black Goo.

The Derelict and Xenomorph share a similar Aesthetic.. yet the Juggernaught and Black Goo creations do not... only if the more Mechanical nature of the Juggernaught was combined with the Black Goo more Organic Look would we then get a DERELICT...

The Derelict and Xeno hives are connected...  and the Juggernaught is Ancient and so a unholy combining of Machine and Matter could happen to evolve the Juggernaughts?

We should not assume that the Xeno Mechanics must come from a Synthetic... and then if this is so... can we assume only Mankind has ever created Synthetic Life?

the other thing to consider is the Worms and Goo... both have been around prior to Prometheus landed on LV-223 in 2093

The Juggernaught had Chest Busted Engineers and so we cant rule out the Worms being the culprit. The time line and locations of LV-223 and LV-426 can not be coincidence.

@ Big Dave-

I just mentioned that time travel/parallel world garbage in another thread to tie everything together. Hope that's not the case. Ridley probably never thought this story would still be going back in 1979. 

I read into this wrong but here it is...

Indeed i hope we dont go that route DK

@ Shasta cyclone

Indeed if this is to be considered Cannon (the site has flaws but so does every reference in the Franchise)...

They did have some idea.... and a extra file if considered Cannon, also states that they discovered a signal from LV-426 and that maybe LV-426 has higher rewards at greater risk than LV-223 and a David 8 would be in-bedded with the Prometheus to check out this signal and no one on-board not even Vickers knows about this.

So if these are Canon then David would have been tasked to study that Signal.

Lots of things if we consider as Canon like the above...

And then Holloways Briefing on the Prometheus where he says they discovered clues to a system.. that maybe traces our Origins and by Chance only one System matched the Star Maps..

This System had One Planet that had a Moon that could support life and they arrived there this morning (when they came out of Cryo-stasis).

These clues and actual dialog from the movie unless they completely forget to stick to what has been shown...

Proves the company knew a bit... and also proves Paradise cant be LV-426 or LV-223

Lambert from ALIEN said the Nostromo was in zeta 2 Reticuli system. That's filmed, theatrical cut support. Doesn't get more canon than that. It's at about the 12:52 mark in the film. I'm agreeing with BigDave, just offering more support that neither planet can be Paradise.
