Hello newcomers and elder comers who still question questions from the films questions.
I have brought it upon myself to answer the questions to the film you question because the questions that were questioned doesn't answer your questions.
So any newcomers please read the answers. I have selected the answers from listening to Ridley Scott, Damon Lindelof and Jon Spahits plus many of the answers are common knowledge if you have a brain.
First of all if you have trouble reading the questions are asked and answered by Sean Connery linked below.
Q/A with sean connery and a Hick noob.
Q/ Is it the planet Earth shown in the beginning?
A/ Yes and No my son. In Jon Spaihts script yes but Damon Lindelof and Ridley decided to keep it ambiguous. These beings could have seeded life in hundreds if not thousands or millions of worlds. Plus take note that the landscape seen at the beginning looks exactly like the landscape seen in LV-223 near the end if you look closely. Who knows.
Q/ What is the Engineer doing?
A/ The Engineer is selected to sacrifice his body by drinking an Alien substance that disintegrates his body and destroys his cells creating a cloud of mutating cells to be spread out all over the primordial rocks, Algae and eventually into the water and the mutating cells then reform and create the basis of life.
Q/ But why is he doing it? why create life?
A/ Why did the scientists in Scotland create and clone Dolly the sheep? Why do scientists clone rats, mice and frogs? why did Weyland create androids? there is no purpose for us to do so. It just feels good and it is a major EGO boost to play god and to be worshipped. These are alien beings who most likely think way different than we do.
Q/ The cave paintings in the Isle of Skye. Why did the Engineers paint this and why is it an invitation when it is revealed they wanted to kill us?
A/ It is unknown but heavily hinted that it wasn't actually the humans who drew this. Some of their enslaved humans could have easily witnessed their technology such as the Orrery star map or another theory is that humans may have been brought to LV-223 and made to build temples for the engineers such as the dome pyramid. If your an advanced god like species why build them yourself when you can get some little dumb humans to do it. After all the entire history of humans has been to follow and worship but not lead.
Q/ If Shaw is in Cryostat's then how can she dream?
A/ Well junior. It's because the brain is a muscle and it needs exercise no matter how frozen it is. So scientists in the future developed an idea to extract different types of dreams from an individual and they would replay them over and over again in that persons brain as they slept.
Q/ But that's unrealistic
A/ Well that's because it's the future ya dumb bastard. It's Science Fiction junior!
Q/ Why wasn't David in Cryo?
A/ That is because he's a Robot and has no need for it. His main priorities was to look after the ship and more importantly Peter Weyland and finally to study Charlie Holloway's thesis on the Engineers by learning every known ancient language on Earth in a hope of being able to communicating with them.
Q/ The Weyland speech. Why is he pretending to be dead?
A/ He's not junior. No one ever said he was dead. Weyland recorded the video before they set out and there were fears he could have died whilst frozen. Vickers and David just never told anyone because it's none of their business.
Q/ Why didn't they recon or send drones to survey the planet before entering it?
A/ Maybe they did but it would just slow down the pacing.
Q/ Why didn't they take weapons with them with their first trip out?
A/ So they would take weapons to meet god? bitch you crazy
Q/ Why did they take their helmets off?
A/ Because it was safe to do so. I guess it just represents how cocksure we humans are by trusting out own technology.
Q/ How did David know how to work their panels?
A/ Because he's more intelligent than us and studied their language by breaking down all known ancient languages. Plus he was curious and touched everything.
Q/ Where did the ladder come from?
A/ One of the crew members had it with them on entering the pyramid.
Q/ What where the Engineers running from and what happened to them?
A/ We do not know. Perhaps a mutated comrade? maybe their was also a cure at the other side of that door. There may have been an outbreak on the planet.
Q/ When the door slammed shut why didn't it just crush the engineer's head instead of decapitating it?
A/ If you pay attention closely junior you'll notice that the door is actually thin and before you ask the environment inside the temple room was perfect enough to preserve the head plus it was inside a helmet. An alien helmet mind you
Q/ What is the head monument and the Vases?
A/ We humans have monuments of ourselves and prophets and gods. Maybe this is the same case regarding the engineers. The Vases contain a dark liquid which may or may not be the exact same liquid from the beginning.
Q/ Where did the worms come from?
A/ They are actually explained in the Commentary by Jon Spaihts and Damon Lindelof. The worms are indigenous to the planet so are in actual fact the first Alien life forms they discover which I believe will be in a deleted scene. Milburn was more excited than any of the rest of the group at seeing it.
Q/ What was that large mural all about and what was that green crystal?
A/ Again this is not explained. Maybe a similar scenario happened to couple of engineers that happened to Shaw and Holloway. Maybe an Xeno type creature was eventually created from it at one time in the history of the engineers.
Q/ What was the Mural on the ceiling all about?
A/ When we first see it the mural of a tall being touching a life form seems to be neutral as if in a God creation theme but it then transforms into a more Hostile threatening pose. One is life and one is Death.
Q/ Was the storm caused by the Engineer's technology?
A/ It is strongly hinted that it could have been but Ridley Scott said it's a large sand storm with winds up to 200MPH so I guess it's natural.
Q/ Why did they take the head with them and why didn't they just leave it and come back for it later?
A/ Well because they destroyed the temples atmosphere so the head may have been effected by this and rotted in the space of hours like the 'ice man' when it defrosted. Plus I guess the excitement of finding a preserved GOD took over mind and thought.
Q/ why where they in a rush to talk to this being?
A/ Because in a deleted scene showed how Shaw was in a hurry and wanted answers and this was greatly protested by others but Shaw was in charge of their findings remember so she wins.
Q/ How did Fifield and Millburn manage to get left behind and lost?
A/ Well junior it's because they had no map with them and Janek probably thought they were with the others and the others were only in the temple for 5 minutes before leaving. As the rover vehicle left the crew thought that fifield and millburn were on board.
Q/ How could David interact with Weyland if Weyland was dreaming? and what were they talking about?
A/ David can enter people's dreams or modified dreams. In the dream which was cut out of the film Weyland was a young man surrounded by young women. He discussed the mission with Weyland explaining it was failure and he found no answer to making Weyland immortal or younger and Weyland demanded that David try harder and find out if any technology left behind by the engineers could make his ambition happen.
Q/ Why did David spike Holloways drink?
A/ Davids objective was to help Weyland find an answer to becoming young again or immortal and decided to test out this liquid on a guinea pig to see if this liquid would answer his objective. In this case Holloway was the guinea pig. Because David is a robot this allows him to carry out objectives that might be considered unethical.
Q/ Why were the engineers stacked up like that and what were those holes?
A/ We do not know. It is hinted the last remaining survivor (last engineer) went through a Ripley style scenario and before going into cryo it stacked and piled its dead comrades. We simply do not know this answer and it is kept mysterious and frightening. The holes could either have came from the last engineer killing its comrades to quarantine or stop infection or the infected engineers exploded from inside their suits hence the holes.
Q/ Is Vickers a robot?
A/ No she is not. The reason Janek asks this is because with so many robots and because Vickers and David look so much alike so there is a kind of mistrust with the corporation. And if your going to ask me why they look the same I'll answer that too. Weyland made David look like himself and Vickers is his daughter so of course she'll look like David.
Q/ When Holloway has sex with shaw. Is it his saliva that then infects and mutates the food she was eating hence why it looks like an octopus or was it his sperm that mutated inside her?
A/ The writers and Director say sex but it could very well be the food which is quite smart.
Q/ Is that snake thing a proto-chest burster? and why is Millburn acting like an idiot? and what happened to fifield and why didnt he just explode like the engineers?
A/ No! It's just an evolution of the worms that you saw earlier. Millburn obviously connected the dots and knew it was the worms he was excited about earlier and because its a worm he immediately thinks its not dangerous as worms are not predators. Plus I believe it was said in one of the commentaries that in a non filmed sequence, Millburn got stoned alongside Fifield before this. The worm Isn't a killer, worms need warmth to survive and the human body is obviously warm and the temple is below freezing so it makes sense that it tried to get into his suit. It's acid blood spray's over Fifields gorilla glass helmet turning into a mask and he falls into the pool of black liquid. The pool wasn't deep enough for him to drown in so he mutated like the worm. It appears this liquid mutates the exterior of what it touches but disintegrates the interior of whatever it touches.
Q/Was Holloway mutating or disintegrating? and why wouldn't Vickers let him on board?
A/ He was disintegrating but slower than the engineer from the beginning of the film. The sacrificial engineer drunk a lot of the liquid whereas Holloway only drunk just a droplet. Because she didn't want any infection coming on to the ship despite any kind of advancement in treatment. This is an alien disease and who knows what its capable of
Q/ Why didn't the 2 crew members chase Shaw after she beat them and ran away?
A/ Because they were badly knocked out and probably in pain. The Prometheus is a fricken large ship with a maze of corridors. It's not like Shaw just ran around the corner.
Q/ Why was the MEDpod calibrated only for men?
A/ I've heard noobs and boobs say this before. But don't worry Bambie I'll set you right. It's actually for Peter Weyland.
Q/ How come there's characters shooting at Fifield and the same characters are in the room with a recently woken up Weyland at the same time? And it was clearly a woman driving the Rover that ran over the mutated Fifield.
A/ Because it was originally shot like this junior. Shaw gets a C-section, discovers Weyland, they all suit up and head down to the cargo bay via elevator and at the same time Janek discovers Fifield outside. As Fifield tears through the crew, Weyland is rushed into the Rover as the fight goes on. As the driver is killed by a hatchet before he enters the Rover Shaw climbs in the drivers side. Janek and his pilots come out and burn it and Shaw runs him over. They take a few minutes of R&R and Shaw has her speech with Janek.
Q/ Why didn't the engineer speak back to the humans?
A/ He actually did and you can tell the scene was cut and edited as David and Weyland constantly change positions as does the Engineer. But it was ready to set out to kill us all so why would it have a conversation with the species it is about to kill?
Q/ Why wasn't the engineers going to use hi-tech weapons on us? Aren't they aware of our weaponry?
A/ Because Junior 2,000 years ago we fought with swords and still thought the world was flat.
Q/ Why where they wanting to destroy us anyway?
A/ There are several theories given by Ridley and the writers and in clues in the film. They are superior advanced beings and maybe they saw that we were becoming smart and didn't want any future rivals. They probably didn't like the way we grew up in the evolutionary cycle and didn't like the fact we started worshipping false gods and not them and forgot about them. Or we were just an experiment gone wrong and wanted to clear our planet to make way for the next step in evolution.
Q/ Why did Janek just play kamakazi with the Juggernaut without thinking about it?
A/ Let's say your on a small submarine with no weapons and you find a large nuclear submarine in the Ocean and it is currently ascending the Ocean towards the surface to launch a 50 megaton bomb on your home city where your family are. Would you waste time trying to contact your government; by that time it would be too late or would you save your family and millions of lives by colliding with it thus saving everyone? Same thing happened here Junior
Q/ Why didn't Vickers and Shaw run sideways?
A/ You really are a bit derpish junior. They never stood still and stared at the thing and calculated where it would exactly crash. They just did what everyone would do, RUN!! they ran like Forrest Gump and with exploding Debris crashing all around them the adrenaline would take over. Plus the scene was mostly done in slow motion. It only took 8-11 seconds for it to fall and tip over. When it did shaw fell and because of that she was able to see the juggernaut's direction. Vickers however never looked behind her and it was too late.
Q/ Why did the engineer come back for Shaw and not just get into another craft and take off?
A/ Because we managed to take down one of it's crafts. It's not going to leave without making sure any threat is gone.
Q/ Is the trillobite that impregnated the engineer the first Facehugger?
A/ No. The events of Alien would have happened even if the events of Prometheus never happened meaning the Xenomorph eggs were around thousands of years before hand.
Q/ Why is Shaw going to the engineers home world instead of our own home world?
A/ She has nothing left except her faith. Everything she has ever known has died and all she has left is her painful memories and her questions.
Q/ Was that a queen Xenomorph has exploded from the engineer? and why was the engineers body not anywhere near the Trillobite? and why was the lights going on and off?
A/ It isn't an Xenomorph. It's just a strange looking creature. It's more humanoid and organic looking than the Xeno and has five human like fingers. Like Kane the engineer could have woken up and wondered off before collapsing followed by the chest burst. We don't know how long it has been since the trillobite face raped him. The Trillobite could have been feeding him air for months who knows or even years. by the time of the chest burst maybe the power to the ship was failing.
Q/ Is this a prequel to alien?
A/ No. A prequel means a series of events that lead directly to the start of or cause the beginning of an original story. Think of the Alien Cannon as the letter 'T'. The beginning of Alien is the path to the right but Prometheus goes left into new uncharted waters or space should I say.
Q/ So this is definitely not the same planet or spaceship or space jockey/engineer from Alien?
A/ No. Nothing to do with the plot of Alien. But maybe the ship in Alien was the only engineer ship that took off on its course to destroy Earth but something happened causing a facehugger to attack the engineer during it's journey. Or perhaps this incident happened long before they decided to wipe out the Earth and our species.
Q/ So Peter Weyland. Is he a relative to the Weyland character from AVP?
A/ No. Alien VS predator is not part of the alien universe and no matter how many references the predator films degrade themselves with will make any difference.
Q/ But AVP. . .
A/ Fuck off
