Why did the Engineers in the control room of the ship not take off and go to Earth 2,000 years ago?
Because the entire damn facility was under quarantine, remember? If you've got doors coming down and sealing so hard they decapitate guys, the freaking launch bay doors are not opening up either. The pilots set the ship's navigation to head to earth, then hopped into cryo to wait until a rescue team came. But none did, probably because they abandoned the facility. They knew not to fuck around with this stuff, that's why they put the research facilities on the middle of nowhere in the first place.
Why did the star map lead there, instead of to the Engineer home world?
If you go with the theory that the Engineers were using Earth as a cultivation of some kind, and that they would "reset", or infect the planet when we got technologically advanced enough to reach out to them, why would you give them your home address? They left the directions to a military facility, which would be plenty equipped to handle any expedition party that would reach out, without endangering the home world. It's like leaving them the address to Guantanamo Bay instead of San Francisco.
You got to agree that this part implies that the space jockey race are all on that planet, that there is only a handful of them, or at least that those in charge of mankind are only in that galaxy or whatever. Because otherwise you would expect that the rest of the race would have went and killed mankind, but they never did. We get the impression the waken-up engineer is the last one of them still alive and tries to go carry out the mission.
IMO the ship in Alien is another one that managed to escape, but the pilot was infected and a queen came out, leaving eggs in the ship.
Like I said before, because of Scott's interviews, here is where I think the movies are going:
Engineers = fallen angel, Scott said so. He implied that fall angels do "the cool stuff, get all the chicks, go to the best bars", and that paradise is a much different and troubling place. This implies, figuratively, that the jockeys are doing something VERY different from what the "home world" or paradise is all about. We can clearly see the connection here to Prometheus: fallen angels/nephilim (who rebelled against God, gave taught mankind all this such as war, beauty, etc. Read the book of Enoch, it's basically a 2000 years old sci-fi novel. It's the book from where the whole "fallen angels" notion come from as that story is NOT found in the Bible, unlike most people think. The only thing that echos the book of Enoch in the Bible is the following, which goes into much greater details in the book of Enoch:
Bible:
Genesis 6:1-4
1. When men began to increase in number on the earth and daughters were born to them,
2. The sons of God saw that the daughters of men were beautiful, and they married any of them they chose.
3. Then the LORD said, "My Spirit will not contend with man forever, for he is mortal; his days will be a hundred and twenty years."
4. The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of men and had children by them. They were the heroes of old, men of renown.
Numbers 13:32-33
32. And they spread among the Israelites a bad report about the land they had explored. They said, "The land we explored devours those living in it. All the people we saw there are of great size.
33. We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them."
In Enoch, the following chapter deals with this:
VI-XI. The Fall of the Angels: the Demoralization of Mankind: the Intercession of the Angels on behalf of Mankind. The Dooms pronounced by God on the Angels of the Messianic Kingdom.
All of those myths are in reality based on
Sumerian myths, which is the language closely linked to the one the jockeys write and speak with in the movie.
It's going to be impossible to know until the second movie, but the possibilities are as follows:
1- All space jockeys = fallen angels.
2- Only some of them are fallen, the others remaining on God's side.
If 1 is true, then what happened on the moon was not an accident but a punishment: the fallen angels were attacked by God (in the book of Enoch, the fallen angels and their leader are bonded until judgement day). And this would explain how this may have happened everywhere where the fallen angels had found themselves, and hence why they seem to be all dead. They were all dealt with.
If instead #2 is true, it implies that God fixed the problem (killed/bounded the fallen angels) and the jockeys that are doing his bidding are still out there doing stuff, and that they had no intention of going kill mankind. Less likely, because it would contradict the idea that mankind is wanted dead.
But there is a third possibility, which would be closer to the Islamic version of Genesis, and which might tie into the above but also make more sense in the context of the movie: the angels were told by God that mankind was superior to them, and some of the angels (jinns in Islam) refused to accept this, rebelled, and were punished.
We could see the engineers in the movie as the djinns: they want to wipe out mankind because they have figured God's plan for mankind and reject it. They are basically actively trying to sabotage God's work. They were all stopped, but the one who gets woken up at the end decides to resume his mission.
