Some piece of my mind after watching this movie

this is exactly what i think after watching the movie 1. At beginning on the Movie we saw engineer drinking those black liquid and falling to WATER and some DNA thing spreading and i got the impression this WATERy Planet is EARTH and this is the begining of life in the earth that the movie try to telling us (we all know up until know water is source and origin or all life but there's no one to teach us this) 2. skipping to scene where they investigate the ruins they investigate some mural or statue of xenomorph queen and there is so many tube/container of those black liquidified thing and skipped back a little we watching david messing with engineer equipment and try to learn sumthing from there i know that isnt to open those door only :) i just know the result is we showed some engineer running and the last one is dragged by sumthing and decapitated by the door that emergency closed 2a. in this scene i understand 2 problem they discover black liquid that proved to be origin or substance to fasten the evolution they discover that sumthing is happening that unexpected by the engineer 3. when they comeback from the ruins david gives that black liquid to holloway (to making sumthing we must first destroy<--- i blieve david say sumthing like this and i know that he learn this from the device in the ruins when he trying open the door)and make him contaminated with those and the result is he's death and make shaw pregnant with evoved sperm thats why that thing is like squid :) 4. when the engineer woke up the oldman via the david say that he want to be sumthing like immortal and the engineer is very composed manner to david and see it with care when i see this scene is like,so this is our kind's creation's creation at the moment he think david as lowly lifeform doesnt have any rights to speak to the engineer and with their languange too!! okay lets head to the summary we know engineer created life in earth now so they are origin of our life and they created with their body himself plus the black liquid that faster the evolution now we knew that our and engineer's DNA is the same and identically i begining to think they story like this The Engineer is reaching some point of technology that makes them could do sumthing like creating human buat at somepoint they facing extiction because clash with xenomorph to prevent the extiction they created life in the planet that has water maybe similar with their's and even sacrificed their body to adapting their DNA into this planets we called EARTH the result is human 2000-3000-4000-5000 or maybe later the engineer is come contact with different civilatation to teach them how to live better and even make the "star map" for them (human) in hope that in distant future they will evolving into the engineer itself so the species wont extict in approximately 2000 years ago the engineer society decide than human evolving way too slow!! so the military plan to send those black liquid fast evolution and drop it to earth to faster the evolution of human that already carrying the engineer DNA,to make it faster to their expectation at this point... with those liquid is highly dangered marked material by engineer so they had to moved into LV223 and while in there is some accident that makes those liquid merging with LV223 low Creature and create some xenobirth progress and they forced to cyrogenic sleep and this is where the scene of engineer running to the door and dragged by sumthing maybe xeno creature and decapacitated by the emergency closed door and meanwhile the xenomorph is building some bases and offcourse they had queen and we know xenomorph is no low intellegent creature they know how to worship their queen and the result is those alien queen mural in their ship where it the first outbreak happen after 2000 years maybe those xenomorph already died out or their seed in hibernating condition when the prometheus party come to the ruins they awake those engineer that manage to stay alive after those incident the engineer woke up and find that "this is what we created?,low intellegent yet to demanding such immortal thing?even their creation speak with to me with our language?"its showed how it raged through and still composed to complete their mission to fasten the earth evolution with those liquid and the last scene where the engineer try to reach shaw i bet it is angry because "your low intelegent brain is ruining OUR SHARED existence that we build almost thousand years" maybe he's going to show shaw the files they had in the engineer's ship with david as a translator to showing us human how foolish that we can be, in the end those engineer is death by sperm evolved creature from shaw womb and gives birth for 1 proto xenomorph creature so my conclusion is that black liquid if sumthing to faster evolution if its merging with some human genome or DNA or engineer DNA but the result is various to other creature that will turn out to be xenomorph creature if its used to non human DNA,i mean its the material for engineer's gain after all they realize that the material is too much treat if its used with other DNA pattern because of that they need to fight with the xenomorph centuries and finally lead to their extiction and decide to breed life with their sacrificing engineer in the first place
